VIBRONIC K ZYzzYVAS R QAWWALIS T VIBRONIC C According to Nathan, there are bingos (bonuses) down through the column with Y-L-O.
There is another vibronic and resolved band at 737 nm with a relative intensity to the peak of greater than about 15% [19].
It can be used to identify and quantify compounds which absorb frequencies that are characteristics of their structure such as molecular potential energy surfaces, the masses of the atoms, and the associated vibronic coupling.

We conclude that small-scale vibronic fluctuations in the molecular structures and orientations produce significant energetic overlap between different adiabatic states to drive the system from purely excitonic to purely charge-transfer on a rapid time-scale.
We have recently reported [6] that interstitial [Cl.sub.2] molecules in glassy Si[O.sub.2] give rise to a NIR-range photoluminescence (PL) band at 1.2 eV, distinguished by a characteristic vibronic structure due to a coupling to the Cl-Cl vibrations.

No vibronic structures in the spectra appeared below 150 K, suggesting that the ordering structures of the Alq molecules were preserved by the temperature changes.
