We present a quantitative spectroscopic study of type IIb supernovae (SNe). This type of SNe is distinguishable because their spectra evolve with the phase between one dominated by lines of hydrogen (type II) and one without hydrogen and with strong lines of helium (type Ib). This work is part of a larger study that aims at knowing whether type IIb SNe are a homogeneous group or not. Here we started by obtaining spectroscopic parameters that allow us to characterize SNe IIb. This work is part of the Licentiate thesis of P.J. Pessi.
