INSTRUCTION concerning manipulation of 2D data to derive REMPI spectrum:
To make rempi spectrum, using summed up intensities:
1) Make table, for example wave601 – wave1002) Make a matrix with 0´s, for example: make/O/N=(500,400) rempi2=03) New Table for rempi24) Copy content of all waves (wave601 – wave1000) to matrix rempi2:-> CtrlA->CtrlC (in wave table) ->CtrlA->CtrlV (in matrix table)5) Make data points positive: rempi2=-rempi26) Make contour plot: windows -> new-> Contour Plot...ZWave: rempi2, XWave: calculated, YWave: Wavenumber37) Remove 0´s and numbers from Contor plot: Graphs-> Modyfy contour appearance-> Labels (right) ->none-> Do it:

ExpandedCl+ and HCl+region:
To obtain H35Cl spectrum: sum over points 316 – 321 (see figure above):•Make matrix for 6 points (i.e 316-321): make/O/N=(6,400) rempi2a=0•Edit rempi2a•Copy lines for pnt = 316- 321 in rempi2 matrix•Paste to rempi2a matrix•Transpose (flip) rempi2a matrix: MatrixTranspose rempi2a•Make wave equally long as the rempi2a (400) to contain the intensity sum:Make/N=400/D rempi2aa•AppendToTable rempi2aa•Summing up:rempi2aa=rempi2a[x][0]+rempi2a[x][1]+ rempi2a[x][2]+ rempi2a[x][3]+rempi2a[x][4]+ rempi2a[x][5]
