Abstract

We report Shpol'skii-type luminescence spectra of C₇₀ in n-pentane at 1.5 K with vibronic linewidths of 3 cm⁻¹. The vibronic structure of both fluorescence and phosphorescence has been unravelled. The fluorescence intensity largely shows up in vibronic bands corresponding to transitions to ground-state infrared-active vibrational modes and it is concluded that the first excited singlet state of C₇₀ in alkanes is of A′₂ character.
