(a) Using EXCEL (or some other suitable program) set up a
spreadsheet which computes the line frequencies and inten¬sities of both the AB and X parts of an ABX system for an arbitrary set of parameters.
(b) Use your spreadsheet to compute the spectrum for the following parameters: v0,A = -20 Hz, u0,B = -27 Hz, v0,x = -1000 Hz, JAB = 5 Hz, JAx = 12 HZ and JBx = 3 Hz. Make a sketch of the spectrum (or do so using a computer) and note any features of interest.
(C)Investigate the effect on the spectrum of changing the signs of the various coupling constants
