The relative electron intensities of eight transitions in $sup 144$Nd were measured with a combination magnetic-Si(Li) spectrometer. The deduced internal conversion coefficients were compared with theoretical values in order to determine the multipolarity assignments for these transitions. With the assumption that the 618.0-keV transition is E2, the 476.8-, 582.4-, and 696.5-keV transitions were also found to be E2. The 301.7-, 778.6-, and 814.1-keV transitions were found to be predominantly E1. Our results are consistent with an E0+M1+E2 assignment for the 890.1-keV transition. The internal conversion studies confirm the spin and parity assignments for four excited states in $sup 144$Nd which were previously proposed mainly on the basis of angular correlation measurements.
