Development of VUV tunable laser spectroscopy techniques for characterizing calcium fluoride
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: The large band gap (approximately 11.5-12.1 eV) and high transmission of calcium fluoride (CaF2) crystal in the ultraviolet (UV) and vacuum ultraviolet (VUV) region makes it an important material for ...
Diagnostics in VUV laser spectroscopy
(Stellenbosch : University of Stellenbosch, 2005-03)
A tunable vacuum ultra-violet (VUV) laser source was recently developed for VUV spectroscopy using state selective excitation and total fluorescence detection. The VUV laser source makes use of a four-wave mixing process ...
The investigation of resveratrol with conventional and ultrafast pump-probe spectroscopy techniques
(Stellenbosch : University of Stellenbosch, 2009-03)
An ultrafast pump-probe spectroscopy experiment was developed in order to investigate the fast photoinduced isomerization reaction of the molecule resveratrol. Characteristics of the resveratrol molecule are discussed, ...
Laser spectroscopy of the Fourth Positive System of carbon monoxide isotopomers
(Stellenbosch : University of Stellenbosch, 2006-03)
Carbon monoxide (CO) is a diatomic molecule of particular interest in astrophysics, due to its high abundance in interstellar space. The Fourth Positive System A1Π−X1Σ+ of CO is an important feature in the vacuum ultraviolet ...
Vacuum ultraviolet laser spectroscopy of CO molecules in a supersonic jet
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: A tunable narrow-bandwidth laser source combined with a supersonic gas jet as sample is wellsuited for obtaining high-resolution spectra of cold isolated molecules and complexes. In the present study ...
