Visible fluorescence is produced using an argon-ion laser for excitation in sooting methane/air and methane/oxygen diffusion flames. This emission is attributed to small (two to four ring) polycyclic aromatic hydrocarbons, as suggested by previous studies. The key finding in the present investigatio

Laser-induced fluorescence has been observed form the formaldehyde A' A,-jt 'A, electronic transition in a well characterized, laminar methane/air diffusion flame burning at atmospheric pressure. This represents the first optical measurement in flames of naturally occurring formaldehyde, an importan
Laser-excited molecular fluorescence measurements of CH and CN were made in atmospheric-pressure, acetylene flames. The fluorescence intensity dependence on laser intensity was observed to depart from linearity as laser spectral intensities increased, indicating near saturation. This occurred at las
The characteristics of laser-induced fluorescence (LIF) detection and state-of-the-art conventional fluorescence (CF) detection in the UV region below 300 nm in conventional-size column liquid chromatography are compared. An argon-ion laser system is used to provide four laser lines, i.e. 257 and 29
