The anti-resonance phenomenon in Raman scattering was studied in the preresonance region of an allowed electronic transition. It is shown that the anti-resonance in the scattering of both totally and non-totally symmetric modes can be explained in terms of an analytical model. The necessary and gene

Abstract
The theory of interference effects between preresonance scattering from an intense electronic transition and resonance scattering from a forbidden electronic transition is formulated. A simple closed formula for the crossβsection of a totaliyβsymmetrical fundamental line is derived for the case where the vibrational structure of both electronic transitions is smeared out. This formula reproduces very well recently obtained experimental excitation profiles in such complex compiunds as tris (ethylenediamine) cobalt (III) chloride and tetrabromopalladate ion.

## Abstract The Raman spectra of AMP and UMP have been taken as a function of the laser excitation wavelength at 5145 Γ , 4880 Γ , 4579 Γ , 3638 Γ , and 2572.5 Γ (the first harmonic of 5145 Γ ). The Raman bands of adenine which decrease in intensity upon base stacking or base ordering are shown to deriv
