Lifetime measurements of the 3[sub 1][sup [minus]], 5[sub 1][sup [minus]], and 1[sub 1][sup [minus]] states in [sup 144]Nd show that the absolute [ital E]2 and [ital E]3 transition rates from the 5[sub 1][sup [minus]] and 1[sub 1][sup [minus]] states are consistent with their structure being formed by the coupling of the lowest quadrupole (2[sub 1][sup +]) and octupole (3[sub 1][sup [minus]]) excitations. A level at 2205 keV has been identified as having [ital J][sup [pi]]=4[sup [minus]] and may be another member of this quadrupole-octupole coupled quintuplet. The energy spacing of the quintuplet can be explained by anharmonicities in the quadrupole-octupole interaction and the influence of the [nu][sup 2](2[ital f][sub 7/2],1[ital i][sub 13/2]) configuration.
