There is now a revolution underway in ultra-accurate measurements of frequency and time using optical atomic transitions probed with highly coherent laser light. By suspending a single atomic ion using an electro-dynamic trapping field and reducing its velocity by laser cooling, we can approach, as close as possible, the ideal situation of an isolated and unperturbed quantum system. Laser...

We present a study of the infrared emission spectra of Deuterium Cyanide (DCN) in the 450 to 850 wavenumbers range at 1370 K. Hydrogen Cyanide (HCN) was present as an impurity in the sample. The spectra were recorded using a Fourier transform spectrometer Bruker IFS 120 HR at the Justus-Liebig Universität, Giessen, Germany. A spectrum analysis software called SyMath developed by one of the...

We have re-analyzed the A-band spectra of oxygen and oxygen broadened by nitrogen previously published by our research group [1,2]. We have used a multispectrum fit analysis [3] and different line shape models. The line shape narrowing (Dicke) effects were incorporate using theoretical calculations for the self diffusion coefficients and Maxwell–Stefan diffusion coefficients discussed. We have...

The Fourier transform infrared spectra of the lower infrared vibrational bands of CH$_{3}$SH have been investigated from 650 to 1200 cm$^{-1}$ at 0.001 cm$^{-1}$ resolution employing synchrotron radiation at the Canadian Light Source in Saskatoon. The relative band strengths and structures are remarkably different from those for the analogous CH$_{3}$OH relative, with the CSH bend being very...
