โฆ Synopsis
The intensity ratio of two Raman bands was measured at various resonant excitation wavelengths for the radical cation of naphthalene. By comparing the observed intensity ratio with calculation, the partitioning of the electronic spectral width into homogeneous and inhomogeneous components was performed.

The processes of radical formation in N-methylmorpholine-N-oxide monohydrate (NMMO) and cellulose/NMMO solutions were studied by ESR at 77 K under high-power UV (lambda = 248 nm) excimer laser flash photolysis. Radicals mainly generated were attributed to the nitroxide type radicals -CH2-NO\*-CH2- a
