3.8 (a) How do isotopes of the atoms affect rotational and vibrational spectra of molecules? Calculate the isotopic shift of 13C160 from the main isotope 12C160 vibrational band. (b) Show that Biskope = p Be, where . ul p= u isotope (Consider diatomic molecules only.) (c) Why do molecules that contain light atoms have rotational and vibrational bands that are broad compared with those of molecules of all heavier atoms?
