Infrared Spectrometry - Chemistry

DefinitionExampleFeaturesPropertiesMechanismInfluencesThe equation on the right describes the major factors that influence the stretching frequency of a covalent bond between two atoms of mass m1 and m2 respectively. The force constant (f) is proportional to the strength of the covalent bond linking m1 and m2. In the analogy of a spring, it corresponds to the springstiffness. For example, a C=N double bond is about twice as strong as a C-N single bond, and the CN triple bond is similarly stronger than the double bond. The infrared stretching frequencies of these groups vary in the same order, ranging from 1100 cm-1 for C-N, to 1660 cm-1 for C=N, to 2220 cm-1 for CN.Get price
