Model atmospheres and synthetic spectra are used to calibrate photoelectric measurements of the C2 Swan bands in spectra of G and K giants obtained by Alexander & Branch. The calculations confirm the anticipated high sensitivity of the measured parameter, the 'c-index', to the chemical composition. The atmospheric parameters effective temperature, surface gravity and iron-to-hydrogen ratio, derived by others from narrow-band photometry, are used to predict values of the c-index for a sample of stars on the null hypothesis. The predicted and measured indices are well correlated, and departures from the null hypothesis are evidently small. The controversial star mu Leo has strong C2 bands, consistent with the null hypothesis and the high values of the iron-to-hydrogen ratio.
