  • Astrophysical molecule CN: vibronic transition probability parameters 
    Karthikeyan, B; Balachandra Kumar, K; Rajamanickam, N; Bagare, S. P (Astronomical Society of India, 2006-06)
    Astrophysical applications are broadened by the emerging consensus on the vibration-electronic (vibronic) transition probability parameters such as Franck - Condon (FC) factors & r - centroids of some molecular species ...
  • 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 ...
  • Identification of AlF Molecular Lines in Sunspot Umbral Spectra 
    Bagare, S. P; Balachandra Kumar, K; Rajamanickam, N (Springer, 2006-03)
    High resolution FTS sunspot umbral spectra from NSO/Kitt Peak were used to detect rotational lines due to 11 electronic transitions of the molecule AlF, in the wavelength region 4400 9000 Å. The presence of lines due to ...
  • Identification of beryllium hydride isotopomer lines in sunspot umbral spectra 
    Shanmugavel, R; Bagare, S. P; Rajamanickam, N; Balachandra Kumar, K (Astronomical Observatory, Serbia, 2008-06)
    A high resolution spectrum of FTS sunspot umbra of NSO/Kitt Peak was used to conduct a search for the molecular absorption lines due to BeH, BeD and BeT isotopomers. Analysis led to estimates of identification of the ...
  • Presence of LaO, Presence of LaO, ScO and VO molecular lines in sunspot umbral spectra 
    Sriramachandran, P; Bagare, S. P; Rajamanickam, N; Balachandra Kumar, K (Springer, 2008-11)
    High-resolution Fourier Transform Spectrometer sunspot umbral spectra of the National Solar Observatory/National Optical Astronomy Observatory at Kitt Peak were used to detect rotational lines from 19 electronic transition ...
  • 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 ...
  • Transition probability parameters for the band systems G, H and I-B of astrophysical molecule PO 
    Rajamanickam, N; Balachandra Kumar, K; Shanmugavel, R; Sriramachandran, P; Nagarajan, K; Bagare, S. P (Springer, 2003-06)
    The transition probability parameters, Franck - Condon factors and r-centroids, have been evaluated by the more reliable numerical integration procedure for the bands of G, H and I-B systems of astrophysical molecule PO, ...
