The phosphorcsccncc spectrum of xdnthonc cmbeddcd in a polycrystallinc matrix of n-hcxanc has been measured at 77 and 4.2 K. Dramatic diffcrcnccs in spectral features and triplet lifetime arc evident at these two tempcraturcs. The cmitting species at 4.2 K is assigned as predominantly 3(zz\*) in cha

Highly resolved absorption. fluorcscencl: and phosphorescence spectra of coroncne molecules dissolved in a triphenylene solid-state matrix have been observed at 4.2"K. It is found that each spectrum is composed of two subspectra with difkrent polarization: one of them, subspecrrum I, consists of the
The aldehydc group out-of-plane vibrational activity in 3nn.f -c S, phosphorescence of p-chlorobenzaldehyde in p-sylene and acetophenone matrices at 4.2 K was examined. The 7 CHO vibration was found to be very sensitive to the matrix, being very strong in acetophenone and absent (or weak) in p-xylen
