  • Astrophysically Useful Parameters for Some Vibronic Transitions of AlH and BH 
    Karthikeyan, B; Raja, V; Rajamanickam, N; Bagare, S. P (Springer, 2006-12)
    For molecular identification in astrophysical sources, an astrophysicist needs some spectroscopic parameters such as dissociation energy, vibrational or rotational temperature of the source, band or line wavelengths, ...
  • Evaluation of the effective temperature of sunspots using molecular parameters of AlF 
    Balachandra Kumar, K; Raja, V; Karthikeyan, B; Bagare, S. P; Rajamanickam, N (Hindawi Publishing Corporation, 2015-07-07)
    The physical conditions of celestial objects can be analyzed using the spectrum of atoms or molecules present in the object. The present work focuses on the spectroscopic analysis of astrophysically significant molecule ...
  • On the Franck-Condon factors and R-centroids of the astrophysically interesting molecule CS 
    Karthikeyan, B; Raja, V; Rajamanickam, N; Bagare, S. P (National Library of Serbia, 2007-12)
    In molecular astrophysics, the Franck-Condon (FC) factors and r-centroids are essential for the interpretation of spectral intensities in terms of emitting astrophysical source conditions. They have been evaluated for the ...
  • On the search for BF, BH and BS molecular lines in sunspot spectra 
    Karthikeyan, B; Bagare, S. P; Rajamanickam, N; Raja, V (Elsevier, 2009-02)
    A search has been carried out for the presence of rotational lines of boron containing diatomic molecules BF, BH and BS in the high resolution Fourier Transform Spectra of sunspots observed at the National Solar Observatory ...
  • Transition Probability Parameters for Certain Band Systems of the Astrophysical Molecule PO 
    Balachandra Kumar, K; Raja, V; Nagarajan, K; Bagare, S. P; Rajamanickam, N (Institute of Theoretical Physics and Astronomy of Vilnius University, 2002)
    The transition probability parameters, Franck-Condon factors and r-centroids have been evaluated by a new more reliable numerical integration procedure for the bands of the PO molecule in the ultraviolet region (1800--2900 ...
