Generally, a PHB hole consists of three parts (6), that is, a zero-phonon hole, which is a sharp hole emerging at the irradiation frequency and which is create by a photoreactive guest molecule whose zero-phonon line exists at the laser frequency; a phonon side hole, which possesses a broad hole emerging at the higher energy side of zero-phonon hole and which is created by the phonon side band of the same guest molecule that produces the zero-phonon hole; and finally a pseudo-phonon hole, which is a broad hole emerging at the lower energy side o the zero-phonon hole and which is created by molecules whose phonon side band exists at the laser frequency.
In the weak interaction system, one phonon process is dominant in the phonon side band absorption so that the energy difference between the zero-phonon hole and its pseudo-phonon side hole reflects the energy of a phonon mode, i.
The vibronic energy level can be detected by the energy difference between the zero-phonon hole and the satellite hole (23).
