描述了一种从实验光谱数据拟合碰撞线宽和位移的技术。该方法涉及卷积的低压参考光谱与洛伦兹形状函数和比较卷积的光谱与较高的压力谱。给出了几个实验实例。该方法的一个优点是不需要关于仪器响应函数或光谱调制的额外信息。此外，该方法被证明是相对不敏感的样品池中的反射的存在。
A technique is described for fitting collisional linewidths and shifts from experimental spectral data. The method involves convoluting a low-pressure reference spectrum with a Lorentz shape function and comparing the convoluted spectrum with higher pressure spectra. Several experimental examples are given. One advantage of the method is that no extra information is needed about the instrument response function or spectral modulation. In addition, the method is shown to be relatively insensitive to the presence of reflections in the sample cell.
