摘要
介绍一种用VisualBasic6.0实现快速Voigt拟合的方法,并理论计算了甲烷位于1637.64～1637.85cm-1(真空中)的2v3带R9支的直接吸收谱,和实验测得的数据进行了比较,实验结果与理论计算吻合较好,结果表明VisualBasic6.0和Fortran6.0相比完全能够满足精度需要,充分验证了Voigt展宽理论,以及R.J.Wells的算法在误差范围内的正确性。此拟合方法可运用到气体光谱研究当中去。
A rapid method of Voigt fit is acquired by employing Visual Basic 6.0.By using it,the direct absorption spectra of methane at 2v_3 band R9 manifold are calculated within the wavelength range of 1637.64～1637.85cm^(-1)(in vacuum)from the theory,and the calculated results with those measured from the experiment are compare.The experimental results are in fairly agreement with theoretical calculation.The conclusion shows that Visual Basic 6.0 in comparison with Fortran 6.0 can fully satisfy the needed precision.It confirms that the mechanism of Voigt broadening and the rapid algorithms of R.J.Wells are valid.The fit method can be applied to the study of gases spectra.
