Abstract. This paper presents the H band near-infrared (NIR)
spectral library of 135 solar type stars covering spectral types O5-M3
and luminosity classes I-V as per MK classification. The observations
were carried out with 1.2 meter Gurushikhar Infrared Telescope (GIRT),
at Mt. Abu, India using a NICMOS3 HgCdTe 256 x 256 NIR array based
spectrometer. The spectra have a moderate resolution of 1000 (about 16
A) at the H band and have been continuum shape corrected to their
respective effective temperatures. This library and the remaining ones
in J and K bands once released will serve as an important database for
stellar population synthesis and other applications in conjunction with
the newly formed large optical coude feed stellar spectral library of
Valdes et al. (2004). The complete H-Band library is available online
