Question
Chapter 15, Problem 15.9YT
Interpretation Introduction
Interpretation:
A fourth peak in Figure 15-12 is to be chosen and annotated with the approximate frequency of the type of vibration it represents.
Concept introduction:
IR spectrum shows the absorption bands corresponding to the photons of different energies that excite various vibrational modes. The spectrum shows a plot of % transmittance as a function of the wavenumber (reciprocal of frequency) of the IR radiation absorbed.
