Electrical anharmonicities of diatomic molecules
Abstract
The treatment of Herman and Wallis for evaluating the effect of vibration-rotation interaction on line intensities is extended by adding an electrically anharmonic term to the dipole moment function. It is shown how this anharmonicity can be uniquely determined from line intensities of overtone vibration-rotation bands. The method is applied to data of HCl, CO, HBr, and HI, yielding electrical anharmonicities consistent with those ambiguously obtained from band intensities.
