A sample of pure 1 H79Br gas was analysed using IR and NIR absorption spectrometers. A fundamental vibration at 2575.15 cm–1 and an overtone band at 5022.78 cm–1 were measured. (a) Using this data, calculate the equilibrium oscillation frequency (in cm–1) and the anharmonicity constant ( e x ) for pure 1 H79Br.
