Vibrational Intensities. V. BrCl and ICl

摘要

The intensity coefficients,A1, of the fundamental vibrational bands of BrCl and ICl have been measured. From these, the derivativespprime; have been calculated. An upper limit has been set for the overtone intensity coefficients,A2, and the second derivativespPrime;. The values are: for BrCl,A1= 105 cm/millimole,A22.5 cm/millimole,pprime; = plusmn;0.78 debye angstrommdash;1, verbar;pPrime;verbar; 10 debye angstrommdash;2; for ICl,A1= 650 cm/millimole,A24 cm/millimole,pprime; = plusmn;2.1 debye angstrommdash;1, verbar;pPrime;verbar; 14 debye angstrommdash;2.
