Raman studies of thiourea [SC(NH2)2] crystal

Raman scattering intensities of thiourea crystal are found to vary by a factor of up to 105 depending on the vibrational bands, and appropriate gain selections are prerequisite in the measurements to properly observe the whole range of Raman spectra extending from 20cm-1 to 3500cm-1. Some weaker ban...

Raman scattering intensities of thiourea crystal are found to vary by a factor of up to 105 depending on the vibrational bands, and appropriate gain selections are prerequisite in the measurements to properly observe the whole range of Raman spectra extending from 20cm-1 to 3500cm-1. Some weaker bands are first detected in the present work on the polarization dependence of Raman spectra of thiourea [SC(NH2)2] crystal at room temperature. Ausführliche Beschreibung
