Absorption intensities and complex refractive indices of crystalline HCN, HC 3N, and C 4N 2 in the infrared region
Abstract
Absorption intensities of thin crystalline films of HCN, HC 3N, and C 4N 2 are given in the infrared region (4000-45;0 cm -1). The transmission spectra were corrected for scattering and inhomogeneity within the films. The complex refractive indices, n and k, were determined using a program that performs iterations of the Kramers-Kronig integral by utilizing a point-by-point least-squares fitting of the experimental transmission data. Transmission spectra generated using these n and k values reproduce the experimentally observed transmission data to within ±2%.
