Raman spectra of kaolinite and of the formamide-intercalated kaolinite were obtained at both 298 and 77 K using a Raman microprobe equipped with a thermal stage. Upon cooling to 77 K, the band attributed to the inner hydroxyl shifts by 5 cm-1 to lower wavenumbers and the bands assigned to the inner
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
