The reduced mass for the bond C-H needs to be determined the equation 8.4 needs to be used for predicting the value of ν ¯ C − H equals to 3040/cm. Concept introduction: There is a large variance in force constant when there are small differences in bond length. It is known that wavenumber is inversely proportional to square root of reduced mass. With an increase in reduced mass, there is a decrease in wavenumber. Reduced mass is considered as the quantity which allows the two-body problem to be solved as one body problem.
