“…Since VC has four electronic absorption bands between 270 and 400 nm [7], the use of a monochromatic photolysis source can eliminate complications from the possibility that the photochemistry of VC might vary depending on which electronic transition is excited. For example, changing the photolysis wavelength appears to alter the intermediates formed by photolysis of transRhCl(PMe 3 ) 2 (CO) both in solution [8,9] and in lowtemperature glasses [10].…”
