A RAMAN SPECTROSCOPIC STUDY OF THE PHOTODIMERISATION OF TRANS-CINNAMIC ACID AND ITS DERIVATIVES
Allen, S. D. M.; Almond, M. J.; Gilbert, A. ( 1999 )The photolysis of trans-cinnamic acid has been known for many years to yield the $dimer^{a}$. However the nature of the dimer is known to depend on the orientation of the monomers within an individual crystal of the starting ... -
RAMAN SPECTROSCOPY OF FLOURENE UNDER PRESSURE
Chan, I. Y.; Dernis, Mitchell S.; Prass, B.; Stehlik, D. ( 1995 )Studies of a photo-excited H-tunneling reaction in acridine doped flourene have predicted the presence of a $B_{1}$ intra-molecular promoting mode, with a "butterfly" like mode pattern around $100 cm^{-1}$ in $flourene^{1}$. ... -
