New fissile mediums of tunable lasers on basis of derivative yulolidincoumarine

We have studied the influence of the structural and molecular factors of a new derivative of yulolidine on their spectral and generic features in requirements of coherent initiation by excimer XeCl-laser and vacuum-tube pump. The dimensional stabilization of nitrogen atom by yulolidine kern 7-N(CH/sub 2/)/sub 6/ provides a high degree of molecular coplanarity of coumarine. There is a natural bathochromic bias of absorption spectrum and luminescence (on 15-20 nm) and also considerable quantum yield. We have studied the influence of an acid-base equilibrium on spectroscopic and general features of linkage are investigated.
