First identification of the a1Δg–X3Σg− electric quadrupole transitions of oxygen in solar and laboratory spectra
Abstract Electric quadrupole transitions in the a 1 Δ g – X 3 Σ g − band of 16O2 near 1.27 μm are reported for the first time. They were first detected in atmospheric solar spectra acquired with aExpand

A water isotope (2H, 17O, and 18O) spectrometer based on optical feedback cavity-enhanced absorption for in situ airborne applications
Measurements of the isotopic composition of water are thought to help explain stratospheric aridity and related issues in atmospheric sciences. Simultaneous in situ measurements of 2H/1H, 17O/16O,Expand

The absorption spectrum of water near 750 nm by CW-CRDS: contribution to the search of water dimer absorption.
The absorption spectrum of natural water vapour around 750 nm has been recorded with a typical sensitivity of 3 x 10(-10) cm(-1) using a cw cavity ring down spectroscopy set up based on a Ti:sapphireExpand
