Abstract : Few organic compounds of selenium are known and, consequently, very little published data are available concerning the various vibrations around the selenium atom. The paper discusses the C=Se vibration in selenosemicarbazones by comparing their infrared spectra with those of corresponding Se-benzyl derivatives in which the C=Se group has been replaced by a C-Se-Bz. On this basis, it can be seen that a band at 800-780 cm in the spectra of selenosemicarbazones is absent in the spectra of the benzyl derivatives. This band is assigned to the C=Se vibration.
