SPECTROSCOPY


“Spectroscopy” is considered the analysis of material, substance or matter through the observance of how it responds to different wavelengths. The response may be reflection, absorption, scattering, etc.

Visible and near-infrared spectroscopy is growing at a very fast pace in many fields including forestry, medical, agriculture, defense, homeland security, and food safety.

There are many different types of Spectroscopy.

TYPES OF SPECTROSCOPY


Types of spectroscopy are distinguished by specific applications or implementations: (https://en.wikipedia.org/wiki/Spectroscopy)

Acoustic resonance spectroscopy is based on sound waves primarily in the audible and ultrasonic regions Auger spectroscopy is a method used to study surfaces of materials on a micro-scale. It is often used in connection with electron microscopy.

Cavity ring down spectroscopy

Circular Dichroism spectroscopy

Coherent anti-Stokes Raman spectroscopy (CARS) is a recent technique that has high sensitivity and powerful applications for in vivo spectroscopy and imaging.[4]

Cold vapour atomic fluorescence spectroscopy

Correlation spectroscopy encompasses several types of two-dimensional NMR spectroscopy.

Deep-level transient spectroscopy measures concentration and analyzes parameters of electrically active defects in semiconducting materials

Dual polarisation interferometry measures the real and imaginary components of the complex refractive index

Electron phenomenological spectroscopy measures physicochemical properties and characteristics of electronic structure of multicomponent and complex molecular systems.

EPR spectroscopy

Force spectroscopy

Fourier transform spectroscopy is an efficient method for processing spectra data obtained using interferometers. Fourier transform infrared spectroscopy (FTIR) is a common implementation of infrared spectroscopy. NMR also employs Fourier transforms.

Hadron spectroscopy studies the energy/mass spectrum of hadrons according to spin, parity, and other particle properties. Baryon spectroscopy and meson spectroscopy are both types of hadron spectroscopy.

Hyperspectral imaging is a method to create a complete picture of the environment or various objects, each pixel containing a full visible, VNIR, NIR, or infrared spectrum.

Inelastic electron tunneling spectroscopy (IETS) uses the changes in current due to inelastic electron-vibration interaction at specific energies that can also measure optically forbidden transitions.

Inelastic neutron scattering is similar to Raman spectroscopy, but uses neutrons instead of photons.

Laser-Induced Breakdown Spectroscopy (LIBS), also called Laser-induced plasma spectrometry (LIPS)

Laser spectroscopy uses tunable lasers[5] and other types of coherent emission sources, such as optical parametric oscillators,[6] for selective excitation of atomic or molecular species.

Mass spectroscopy is an historical term used to refer to mass spectrometry. Current recommendations[7] are to use the latter term. Use of the term mass spectroscopy originated in the use of phosphor screens to detect ions.

Mössbauer spectroscopy probes the properties of specific isotopic nuclei in different atomic environments by analyzing the resonant absorption of gamma-rays. See also Mössbauer effect.

Neutron spin echo spectroscopy measures internal dynamics in proteins and other soft matter systems

Photoacoustic spectroscopy measures the sound waves produced upon the absorption of radiation.

Photoemission spectroscopy

Photothermal spectroscopy measures heat evolved upon absorption of radiation.

Pump-probe spectroscopy can use ultrafast laser pulses to measure reaction intermediates in the femtosecond timescale.

Raman optical activity spectroscopy exploits Raman scattering and optical activity effects to reveal detailed information on chiral centers in molecules.

Raman spectroscopy Saturated spectroscopy

Scanning tunneling spectroscopy

Spectrophotometry

Time-resolved spectroscopy measures the decay rate(s) of excited states using various spectroscopic methods.

Time-Stretch Spectroscopy[8][9]

Thermal infrared spectroscopy measures thermal radiation emitted from materials and surfaces and is used to determine the type of bonds present in a sample as well as their lattice environment. The techniques are widely used by organic chemists, mineralogists, and planetary scientists.

Ultraviolet photoelectron spectroscopy (UPS)

Video spectroscopy

Vibrational circular dichroism spectroscopy

X-ray photoelectron spectroscopy (XPS)

SPECTROSCOPY ANALYSIS WITH LIGHT ENERGY


Some types of “Spectroscopy” are used for material, or matter, analysis using light energy. Comparison analysis is performed through reflection, absorption, fluorescence, refraction or

scattering of light from interaction with a material sample. Includes Raman

RAMAN SPECTROSCOPY


Raman Spectroscopy is the Focus of our Discussion

A measure of Wavelengths of Light Energy Scattered from Molecules. The wavelengths are shifted from the Incident Light by the Energies of the Molecular Vibrations.

Maybe used for Molecular Determination, including Qualitative, and Quantitative Analysis.

Raman Scattering Amount is Very Weak

Raman Spectroscopy Applications

Biomedical – (Vital Signs Monitoring, Early Disease Detection, Glucose Monitoring, Imaging, Dental)

Homeland Security (Poisonous Gas Detection, Bomb Detection)

Geology

Law Enforcement (Drug Identification)

Food Industry (Contamination, Ripeness)

Pharmaceutical Industry (Correct Prescription Refills, Trace Elements)

RAMAN SPECTROSCOPY


Raman spectroscopy is experiencing very strong growth, because it is noninvasive, highly sensitive, fast, and less sample preparation time required.

This strong growth has resulted in increased spectrometer sales, and increased demand for photonics/laser technicians with a skill set in the field of spectroscopy.
