在0.57μ到11.8μ的波长范围内，在19°、25°和31°C附近的三个温度下测量了As2S3样品的折射率。五项Sellmeier色散方程被用来拟合降低到25°C的平均数据；其中四个常数被选择来近似紫外光和可见光中的吸收连续谱，而第五项被任意选择作为红外吸收边之外的吸收连续谱。为了比较，还得到了另外两个样品在可见光区域的折射率。
The refractive index of a sample of As2S3 was determined at three temperatures near 19°, 25°, and 31°C for selected wavelengths in the range 0.57 μ to 11.8 μ. A five term Sellmeier type dispersion equation was fitted to the averaged data reduced to 25°C; four of the constants were chosen to approximate an absorption continuum in the ultraviolet and visible while the fifth term was arbitrarily chosen as beyond the infrared absorption edge. The indexes of refraction in the visible region of two other samples were obtained for comparison.
