Abstract
IR intensity formulae can be derived in the formI=L′ A; I being square root of intensityI 2, has sign ambiguity. Equations likeI′ I=A′ LL′ A=A′ GA have been used to solve the sign ambiguity. There is only one equation for each species. This position has now been improved by introducing a new concept about this sign ambiguity and solved for electro-optical parameters taking a pair of molecules CHCl3 and CDCl3 for demonstration. This incidentally solves the sign ambiguity problem of polar tensors which are calculated for these molecules.
