β¦ Synopsis
The T + So absorption spectra of ap-terphenyi Crp) crystal at 77 K and room temperature were measured-These spectra were compared with the T c So absorption and phosphorescence spectra of TP in solutron. Tke comparison of these spectra gave some mfo~ation about the potent& curves of TP molecuies as a function of the angle between the outer and central benzene rings both ~fl the trxpIet and ground state.
