of IR absorption bands are characteristic of specific types

of chemical bonds.

An IR spectrophotometer is an instrument which is designed to

obtain an infrared spectra of a molecule. An IR spectra is obtained by

first irradiating a sample with an IR source of light. The light passes

through the sample, which can be in solution or contained within a

salt plate, and then onto an IR light detector. The spectrum is

analyzed by examining at which frequency the peaks occur. Different

peak frequencies indicate different types of vibrational motion and

hence, different types of chemical bonds. The peak intensities are

usually noted as percent transmittance which compares the amount of

light absorbed compared to the amount of IR light that was not

absorbed. The frequencies are normally listed in wave numbers (in

units of reciprocal centimeters).

Experiment

The oxidation of cyclohexanol by dichromate occurred in the
