Comparison of the best-fitting Gaussian (dashed–dotted line), Lorentzian (dotted line), and Voigt (dashed line) band profiles to the HDO band measured at 80 K (red line). The Voigt profile provides a closer match to the HDO band than the Gaussian or Lorentzian profile, thereby enabling us to provide analytical expressions for HDO effective optical constants using Equations (3)–(7) and Table 1.
