Spectroscopic observations are presented showing evidence of mass transfer activity in Algol-type eclipsing binaries. Traditional Hα emission line spectroscopy is discussed along with absorption line spectroscopy of the O I 7774 A multiplet. Eclipse effects in both lines are discussed, along with a new non-LTE model for Hydrogen line spectrum synthesis.
