HBr will exhibit a pure rotation (microwave) spectrum True Vibration-rotation coupling is mainly responsible for the unequal spacing between the observed rovibrational transitions in the IR spectrum of the fundamental band in HBr True The energy spacings between vibrational states become smaller as the J quantum number increases False Anharmonicity Read more…
