Time-resolved dual-broadband picosecond pure rotational CARS has been applied to measure self-broadened S-branch N2–N2 Raman linewidths in the temperature range 294–1466 K. The coherence decays were detected directly in the time domain by followi

The development of time-resolved dual-broadband pure-rotational coherent anti-Stokes Raman spectroscopy using picosecond laser pulses is investigated for use in the study of highly sooting flames. Axi-symmetric ethylene and propane diffusion flames w

The common misconception that hydrogen flames are not visible is examined. Examples are presented of clearly visible emissions from typical hydrogen flames. It is shown that while visible emissions from these flames are considerably weaker than those

We investigate the 205-nm photolytic production of atomic hydrogen in methane flames. This process represents a significant interference in two-photon, laser induced-fluorescence (TP-LIF) detection of atomic hydrogen in flames. Relative TP-LIF profil

Applications of metal-organic frameworks (MOFs) require close correlation between their structure and function. We describe the preparation and characterization of two zinc MOFs based on a flexible and emissive linker molecule, stilbene, which retain

Interference-free planar laser-induced fluorescence measurements of atomic oxygen are demonstrated in steady and unsteady laminar premixed methane flames. Two-dimensional LIF measurements of atomic oxygen present a challenge because of the relatively

Two-color polarization spectroscopy was used to investigate rotational energy transfer (RET) and relaxation of orientation and alignment in the ground electronic state of OH in an atmospheric-pressure methane–air flame. Two independently tunable la

This study reports on photochemical interferences affecting atomic oxygen detection using two-photon laser-induced fluorescence at 226 nm. In contrast to previous studies in which molecular oxygen was proven to be the relevant photochemical precursor

Two-color polarization spectroscopy (TC-PS) and two-color resonant four-wave mixing spectroscopy (TC-RFWM) are used to detect photolytically produced CH3 radicals. An infrared laser pumps individual lines in the ν3 fundamental of the X 2 A 2 ″ sta

We have experimentally investigated three types of two-color techniques for the detection of the hydroxyl radical using an infrared laser to pump individual ground-state rovibrational transitions and an ultraviolet laser to probe electronic transitio
