Isotopic Ratio Measurements of Atmospheric Carbon Dioxide Using a 4.3 μm Pulsed Quantum Cascade Laser

Not Accessible

Your library or personal account may give you access

Abstract

We report CO2 isotopic ratios (13C, 18O) measured in air using a pulsed quantum cascade laser at 2310 cm-1. Performance is improved by analyzing the deviations between the sample spectra and simultaneously acquired reference spectra.
