Title
An Electro-optic Dual Comb Spectrometer for the Measurement of δ13C in Atmospheric CO2
Abstract
A dual comb spectrometer is presented to precisely detect the stable isotope ratio of 12CO2 and 13CO2 at atmospheric conditions and 4.375 µm wavelength. A precision on the δ13C value of 0.24‰ is achieved.
