| Abstract: | Normal coordinate analyses and force constant calculations were carried out using frequencies of infrared and Raman-spectra of the molecules and ions RAsO32?, RAs(O)(OR)2, RAs(O)(OH)2, RAs(OH)O2?, RzAsO2?, R2As(O)OH, and R'2As(OH)2]+ (R = CH3, R' = C2H5). Comparing bond orders of the AsO bond with those in corresponding phosphorus, selenium and sulphur compounds, we found influences of the electron deficiency effect and of bond polarity. |
