✦ Synopsis

Raman spectra at 298 and 77 K of three uranophane samples from different localities are described and interpreted. The spectra are sample dependent. U-O bond lengths in uranyls are calculated from the spectra and compared with the published data of single crystal structure and EXAFS spectroscopy. Hydrogen-bonding of water molecules and silanols is discussed and the 'proton mobility' in uranophane sheet crystal structure is assumed.

We report on the resonance Raman spectroscopy of mass-selected CrFe. The molecule is isolated by sputtering a CrFe metal target, followed by mass-separation through a Wien filter. Samples are deposited in an argon matrix at 14 K. Raman spectra are obtained at several excitation wavelengths (476.5, 4
