Ars. Valentim et al., A COMPARATIVE-STUDY OF THE BONDING CHARACTER IN THE P4ON(N = 6-10) SERIES BY MEANS OF A VIBRATIONAL ANALYSIS, The journal of physical chemistry. A, Molecules, spectroscopy, kinetics, environment, & general theory, 102(21), 1998, pp. 3690-3696
In the present work the bonding situation within the P4On (n = 6-10) s
eries is studied using a combination of experimental and theoretical v
ibrational analysis. A correlation between the spectra of the compound
s is undertaken, and the shifts of the vibrational frequencies within
the series are analyzed. Our study shows that the frequencies of the m
ost modes involving cage motions increase, when more oxygen atoms are
added to the phosphorus centers. This reflects the reinforcement of th
e cage bonds along the P4On (n = 6-10) series. For a few bands the fre
quencies decrease within the series, and this fact results from the re
duced masses, which become larger with the increasing number of the su
bstituents.
