The influence of the Tbetta level upon fluorescence and laser properties of aromatic compounds
Nijegorodov, N.; Winkoun, D.P.; Nkoma, J.S. (Elsevier Science Ltd http:www.elsevier.com/locate/saa, 2003)Please refer to the attached article for an ABSTRACT. The abstract was not uploaded here due to formula appearance problem in UBRISA. -
The influence of the Tbetta level upon fluorescence and laser properties of aromatic compounds
Nijegorodov, N.; Winkoun, D.P.; Nkoma, J.S. (Elsevier Science Ltd. www.elsevier.com/locate/saa, 2004)The fluorescence and laser properties of seven specially chosen aromatic compounds are studied at 293 ◦C. The quantum yield of fluorescence, γ, decay times, τf , of the deaerated and non-deaerated solutions are measured. ... -

(Elsevier Science Ltd. www.elsevier.com/locate/jphotochem, 2008)Intramolecular processes and fluorescence properties of 32 specially chosen aromatic molecules, different in degrees of planarity and rigidity, but family related in -structure are experimentally and theoretically (using ... -
Simulation of solar radiation conditions in coastal and continental areas by using a new algorithm
Monowe, P.; Nijegorodov, N. (David Publishing Company, http://www.davidpublishing.com/journals_info.asp?jId=1000, 2011)An algorithm developed at the University of Botswana is used to study solar radiation conditions in Namibia, South Africa, Mozambique and Botswana. The synoptic stations chosen for the study differ by meteorological ...
