International audience; At the 10th Thermospheric Ionospheric GEospheric Research (TIGER/COSPAR) symposium held in Moscow in 2014 the achievements from the start of TIGER in 1998 were summarized. During that period, great progress was made in measuri

Changes in vibrational circular dichroism (VCD) were recorded on-line during a chemical reaction. The chiral complex nickel-(–)-sparteine chloride was hydrolyzed to free (–)-sparteine base in a biphasic system of sodium hydroxide solution and chl

Broadband spectroscopy with external cavity quantum cascade lasers beyond conventional absorption measurements

Autor: Marcel Pfeifer, Armin Lambrecht, Felix Axtmann, Johannes Herbst, Werner Konz

Publikováno v: The Analyst. 139(9)

Laser spectroscopy is a powerful tool for analyzing small molecules, i.e. in the gas phase. In the mid-infrared spectral region quantum cascade lasers (QCLs) have been established as the most frequently used laser radiation source. Spectroscopy of la

Chiral colloidal molecules and observation of the propeller effect

Publikováno v: Journal of the American Chemical Society

Chiral molecules play an important role in biological and chemical processes, but physical effects due to their symmetry-breaking are generally weak. Several physical chiral separation schemes which could potentially be useful, including the propelle

Quantum-cascade laser-based vibrational circular dichroism

Autor: Marcel Pfeifer, Steffen Lüdeke, Peer Fischer

Publikováno v: Journal of the American Chemical Society

Vibrational circular dichroism (VCD) spectra were recorded with a tunable external-cavity quantum-cascade laser (QCL). In comparison with standard thermal light sources in the IR, QCLs provide orders of magnitude more power and are therefore promisin
