Abstract
We present radial velocity observations of the dwarf novae KT Per and TZ Pe r, that allow us to improve their orbital parameters. For KT Per we find an orbital period of 0.16265777+/-0.00000001 days and a semi-amplitude K-em = 136+/-6 km s(-1), while for TZ Per an orbital period of 0.2629062 +/- 0.00 00008 days and a semiamplitude K-em = 107 +/- 3 km s(-1) are found.
