The measurement and simulation of water vapor isotopic composition has matured rapidly
over the last decade, with long‐term data sets and comprehensive modeling capabilities …

1. INTRODUCTION Atmospheric aerosols play a key role in the Earth's atmosphere.
Aerosols influence cloud formation and their lifetime, they affect the distribution and amount …

In the short space of 15years since their first demonstration, quantum cascade lasers have
become the most useful sources of tunable mid-infrared laser radiation. This Letter …

Halogen chemistry is well known for ozone destruction in the stratosphere, however reactive
halogens also play an important role in the chemistry of the troposphere. In the last two …

The vast majority of gaseous chemical substances exhibit fundamental vibrational
absorption bands in the mid-infrared spectral region (≈ 2–25 µm), and the absorption of …

We report experimental 2D infrared (2D IR) spectra of coherent light–matter excitations––
molecular vibrational polaritons. The application of advanced 2D IR spectroscopy to …

The study of pure carbon molecules has engaged great interest for many decades. 1
Molecules of this kind were first detected in astrophysical sources over a century ago and …

The editors have assembled a world-class group of contributors who address the questions
the combustion diagnostic community faces. They are chemists who identify the species to …

We have spectroscopically determined breath ammonia levels in seven patients with end-
stage renal disease while they were undergoing hemodialysis at the University of California …

A simple and easy to use method that allows high-finesse optical cavities to be used as
absorption cells for spectroscopic purposes is presented. This method introduces a single …
