An in-beam study of excited states in the transfermium nucleus ${}^{252}\mathrm{No}$ has been performed using the recoil separator RITU together with the JUROSPHERE II array at the University of Jyv\"askyl\"a. This is the second transfermium nucleus studied in an in-beam experiment. Levels up to spin 20 were populated and compared to levels in ${}^{254}\mathrm{No}.$ An upbend is seen at a frequency of 200 keV/\ensuremath{\Elzxh} corresponding to spin 16. We also use an improved systematics to connect the energy of the lowest ${2}^{+}$ state with its half-life and find that the deformation of both ${}^{252,254}\mathrm{No}$ is slightly larger than previously assumed.
