The band absorbance and line absorbance of R branch transitions are obtained from high-resolution Fourier transform measurement of silane and germane local mode overtones (n000), n = 1-5, under proper sample pressures and absorption lengths. The absorption coefficients of these overtones are derived by linear least-squares fitting. The relative intensities of overtones can be satisfactorily reproduced with the bond dipole model containing two adjustable parameters. Copyright 1998 Academic Press.

硅烷和锗烷拉伸泛音态的吸收强度

在适当的样品压力和吸收长度下，从硅烷和锗烷局部模式泛音 (n000)、n = 1-5 的高分辨率傅立叶变换测量获得 R 分支跃迁的带吸收率和线吸收率。这些泛音的吸收系数是通过线性最小二乘拟合得出的。泛音的相对强度可以用包含两个可调参数的键偶极子模型令人满意地再现。版权所有 1998 学术出版社。
