*16-2 Gascous HCl exhibits an IR absorption at 2890 em 'due to the hydrogen-
chlorine stretching vibration.
(a) Culculate the force constant for the bond.
(b) Calculate the wavenumber of the absorption band for HCl assuming the force
constant is the same as that calculated in part (a).
16-3 Calculate the absorption frequency corresponding to the-C-H stretching
vibration trealing the group as a simple diatomic C-H molecule with a fore
constant of k -50X 10 N/m. Compare the calculated value with the range
found in correlation charts (such as the one shown in Figure 17-6). Repeat the
caleulation for the deuterated hond.
*16-4 The wavelength of the fundamental O Hl stretching vibration is about 1.4 pm.
What is the approximate wasenumber and wavelength of the first overtone hand
for the O-H stretch
