The development of infrared standards is an ongoing process in laboratories throughout the
world. This handbook provides lists of standards based on spectra of easily available
molecular species, from the upper end of the microwave region to the near infrared. The …

The sensitivity of molecular fingerprinting is dramatically improved when the absorbing
sample is placed in a high-finesse optical cavity, because the effective path length is
increased. When the equidistant lines from a laser frequency comb are simultaneously …

Molecular fingerprinting using absorption spectroscopy is a powerful analytical method,
particularly in the infrared, the region of intense spectral signatures. Fourier transform
spectroscopy—the widely used and essential tool for broadband spectroscopy—enables the …

Advances in optical spectroscopy and microscopy have had a profound impact throughout
the physical, chemical and biological sciences. One example is coherent Raman
spectroscopy, a versatile technique interrogating vibrational transitions in molecules. It offers …

The spectrum of a laser frequency comb consists of several hundred thousand equally
spaced lines over a broad spectral bandwidth. Such frequency combs have revolutionized
optical frequency metrology and they now hold much promise for significant advances in a …

An ultrashort-pulse Cr^ 2+: ZnSe laser is a novel broadband source for sensitive high
resolution molecular spectroscopy. A 130-fs pulse allows covering of up to 380 cm^-1
spectral domain around 2.4 μm which is analyzed simultaneously with a 0.12 cm^-1 (3.6 …

The ν 4 infrared and Raman bands of CH 3 Cl were analyzed simultaneously. A direct fit
yielded a complete set of constants for CH 3 35 Cl, including A 0= 5.20530±0.00010 cm− 1
and DK=(8.85±0.13)× 10− 5 cm− 1. For CH 3 37 Cl an incomplete set of constants was …

The contribution of the third-generation Fourier spectrometer, built at the Laboratoire Aimé
Cotton and currently at the Laboratoire d'Infrarouge, to meteorological and high resolution
Doppler-limited measurements is reported citing typical examples and the latest …

The high-resolution FT interferometer of the Laboratoire d'Infrarouge at Orsay has been
used to investigate the broadening of N_2O lines in the 4-and 8-μm spectral regions. All
data were taken at both room temperature and 220 K. The uncertainty of the measured …
