A quantitative evaluation of spurious results in the infrared spectroscopic measurement of CO2 isotope ratios

The possible generation of spurious results, arising from the application of infrared spectroscopic techniques to the measurement of carbon isotope ratios in breath, due to coincident absorption bands has been re-examined. An earlier investigation, which approached the problem qualitatively, fulfill...
