Effective Site

The system Ag3PO4-Ag3AsO4 has been studied by X-ray analysis of the powder samples and infrared absorption spectra. Formation of cubic mixed crystals of the substitution type has been found within the whole concentration range. For the tetrahedral anions at the site T(2) lowering of the site-symmetry to the effective site-symmetry C3 has been found on the basis of the site-and factor-group analyses of the space group Td4.

Abstract The infrared spectra of five 3,5-dialkyl phenols, six 2-allyl-3,5-dialkyl phenols, and five 4-allyl-3,5-dialkyl phenols are presented. The characteristic infrared absorption frequencies are tabulated in correlation charts. The hyperconjugation and mass effects of substituent groups are discussed.
