Abstract
The correlation of vibrational frequencies with atomic properties of substituent atoms in the molecular system is critically examined for reality in the light of possible mass effects. The general rule is formulated that only frequencies continuously characteristic of a grouping in the mass–frequency plot can be used in such correlations. Calculated mass–frequency plots are presented for the systems XC≡N, XC≡CX, XC≡CY, X2C=CX2, X2C=O, X2P=O, XCH3, X2CH2, X3CH.Keywords
