The infrared and Raman spectra of a sulfur-resistant NiO/Cr2O3/MgSiO3 methanation catalyst are presented and compared to the spectra of the catalyst after being reduced, sulfided, and tested for methanation activity. The molecular structure of the ca

Raman spectroscopy has been used to investigate the structural changes that two supported molybdenum oxide catalysts undergo upon specific chemical treatments. Molecular MoS2 structures are indicated after sulfidation by a mixture of H 2 H 2 S . Cata

Infrared and Raman spectra of solid B 4 Cl 4 have been measured from 35 to 3500 cm −1 . Raman depolarization measurements were made on a CCl 4 , solution, and two i.r. bands were obtained for the vapor. The i.r. spectrum is surprisingly sparse; onl

An extraction technique for the preparation of alumina-supported iridium and osmium carbonyls from Ir4(CO)12 and Os3(CO)12 is reported. It is concluded that the metal carbonyl species produced are highly dispersed and of small particle size (less tha

The damage from cavitation, which has been an increasing problem with the increasing size of hydraulic structures, often results from neglect in the design of these structures. Such design and construction errors as misalinement of conduits and bound

Tetramethylenecyclobutane-d0 and tetramethylenecyclobutane-d8 have been isolated for the first time. They are white crystalline solids at −22°C, and they rapidly polymerize upon warming to room temperature. Infrared data are reported for the vapor

This study was concerned with a systematic evaluation, through a series of experimental trials, of the angular orientation of the side panels of an operator's console. Since both a single operator and paired operators had to be accommodated, the tria
