  • Some vibrational bands of A-X system of BO molecule in the umbral spectrum of Sun 
    Singh, M; Saha, N; Sharma, C. S (Astronomical Society of India, 1996)
  • Some vibrational bands of B-X system of AlO molecule in the sunspot spectra 
    Singh, M; Chaturvedi, J. P (Astronomical Society of Indian, 1986-09)
    Vibrational transition probabilities, namely Franck-Condon factors and average r centroids, have been evaluated using an approximate analytical method for the B-X system of the AIO molecule. RKRV potential energy curves ...
  • Spectrophotometric observations of some Be stars 
    Singh, M; Sanwal, B (Astronomical Society of India, 1996)
    Using EG & G spectrograph coupled with reticon array detector and Optical Multichannel Analyser (OMA) at the Cassegrain focus of the 104 cm telescope of the U.P. State Observatory, Naini Tal, several well known bright Be ...
  • Spectrophotometric study of the Comet C/1996 B2 Hyakutake 
    Singh, M; Sanwal, B. B (Astronomical Society of India, 1998)
  • Spectrophotometry of the comets C /2000 WM 1(LINEAR) and C /2002 C1 (Ikeya-Zhang) 
    Sanwal, B. B; Kumar, B; Singh, M (Astronomical Society of India, 2002-12)
    Spectrophotometric observations of the coma of the comets Cj2000 WM1 (LINEAR) and Cj2002 C1 (Ikeya-Zhang) were taken during Nov, Dec 2001 and Mar, Apr 2002 respectively with 104-cm telescope of the State Observatory, ...
  • Spectroscopic observations of delta orionis 
    Singh, M (Kluwer Academic Publishers, 1982-10)
    The H α profile in the spectrum of δ Orionis shows phase-dependent changes, with a period of variation equal to the orbital period fo the binary system. The profile shape changes from a normal absorption profile at zero ...
  • Stigmatic mounting of holographic plane grating 
    Singh, M (Tipografia Baccini and Chiappi, 1977-10)
    A Stigmatic mounting of holographic plane has been proposed and its properties have been studied theoretically. In this mounting the observation is to be made about a normal direction and different regions of the spectrum ...
  • Surface photometry of three Wolf-Rayet galaxies 
    Singh, M; Sanwal, B. B; Stalin, C. S (Astronomical Society of India, 2001)
    CCD photometric observations of the Wolf-Rayet galaxies NGC 1741, IIZw40 and IRAS 01003-2238 were taken with 104 cm telescope of the U.P. State Observatory NainiTal using 1024 x 1024 CCD camera in B V R I and H? filters. ...
  • Theory of holographic plane gratings 
    Singh, M (National Institute of Science Communication And Information Resources, 1977-05)
    Theory of holographically recorded plane diffraction gratings (HRPDG) has been presented. In general HRPDG with have curved grooves with variable spacing. The self focussing property of HRPDG has been studied in detail. ...
  • Three-body on-site interactions in ultracold bosonic atoms in optical lattices and superlattices 
    Singh, M; Dhar, A; Mishra, T; Pai, R. V; Das, B. P (American Physical Society, 2012-05)
    The Mott-insulator-superfluid transition for ultracold bosonic atoms in an optical lattice has been extensively studied in the framework of the Bose-Hubbard model with two-body on-site interactions. In this paper, we analyze ...
