摘要

香豆素染料激光化合物常被用作着色剂和喷雾剂的成分。,以及食物的气味。因此,这些化合物在许多领域的重要作用导致了几种旨在促进药物控制和表面生产的方法。溶剂在香豆素性质的改变中起着重要的作用。所研究的光谱性质,以及改变溶剂对该性质的影响已经发表。结果表明:摩尔电子跃迁能随最大吸收波长的减小而增大,以丙酮为溶剂的吸收光谱强度最高;此外,由于“C=O”带、“O=C - O, C - C”和“C - O”形变,在拉曼位移中出现了许多带。涉及“O-H”基团的特征振动是“O-H”和“C-O”部件的拉伸和弯曲模态。

Absorption Spectrum and Raman Spectroscopy of Coumarin507 Dye Laser in Different Solvents
Coumarin dye laser compounds are often used as components in coloring agents and sprays., as well as in the odorization of foods. Therefore, the important of these compounds in many felids leading to growth of several ways aiming to advance the control of pharmaceutical and superficial producing. Solvents play an important role in changing the character of coumarin. The investigated spectral properties, as well as the effect of changing the solvent on this property, have been published. results referred that the molar electronic transition energy increased with decreasing the maximum absorption wavelength, and the highest intensity of the absorption spectrum was in the case of acetone solvent. In addition, many bands appear in Raman shift attributed to the ''C=O'' band, ''O=C–O, C–C'', and ''C–O'' deformation. The characteristic vibrations involving the ''O-H'' group is the stretching and bending modes of the ''O-H'' and ''C-O'' parts.
