On the vibronic level structure in the NO3 radical
Part III.† Observation of intensity borrowing via ground state mixing
Abstract
The Ã2E″← 2A′2
2E′←
2A′2 electronic transition, those to a″1 levels involve only negligible upper-state borrowing effects. Rather, it is the vibronic mixing of the ground vibronic level of NO3 with vibrational levels in the
2E′ electronic state that permit the a″1 levels to be seen in the spectrum. These ideas are supported by vibronic coupling calculations. The fact that the intensities of features corresponding to the two different vibronic symmetries are comparable is thus accidental.
