The measurements of absorption spectra of various powdered materials were carried out by means of a microspectrophotometer. The conditions under which the microspectrophotometer was being operated were discussed. A comparison was made between two transmission curves, one of which the microspectrophotometer was being operated were discussed. A comparison was made between two transmission curves, one of which was obtained by means of a microspectrophotometer and other one was calculated from the diffuse reflection curve obtained by an elliptic mirror method, and the priority of the former method was clarified. The transmission curves obtained by the microspectrophotometer were essentially identical with the diffuse reflection curves. However, the difference between both the curves was remarkable in the region where the absorption was strong, and the structures were observed on the curve obtained by an elliptic mirror method, and the priority of the former method was clarified. The transmission curves obtained by the microspectrophotometer were essentially identical with the diffuse reflection curves. However, the difference between both the curves was remarkable in the region where the absorption was strong, and the structures were observed on the curve obtained by the microspectrophotometer. With respects to the measurements of the optical band gap for powdered (Zn, Cd) S, the band gap was smaller than what had been expected from the molar composition though the lattice constants (Measured by X-ray analysis) were linear functions of the composition. The relation between the band gap and the composition. Possible reasons for this phenomena were discussed.
