Abstract:

In this paper, the quantum energy levels and the level splitting of the first and the second excited states generated by the stretching vibration of CH and CD bonds in normal benzene C6H6 (vapour and liquid) and deuterated benzene C6D6 (vapour and liquid) have been studied in detail by new non-linear quantum mechanical theory in weak disperse limit. The distribution of energy levels of benzene molecules has been also obtained, and is consistent with experimental data.

Key words: Non liner quantum mechanical equation, Quantization, Vibration, Benzene, Quantum energy levels
