The g factors of the $4_1^{+}$ and $6_1^{+}$ states in ${}^{144,148}\mathrm{Nd},$ the $4_1^{+}$ state in ${}^{146}\mathrm{Nd}$ and the $6_1^{+},$ $8_1^{+},$ and ${10}_1^{+}$ states in ${}^{150}\mathrm{Nd}$ have been measured for the first time by projectile Coulomb excitation coupled to the transient field technique. The g factors of the $2_1^{+}$ states of ${}^{144,146,148,150}\mathrm{Nd}$ have been remeasured with high precision. The data clearly indicate that, while ${}^{148,150}\mathrm{Nd}$ are well described by collective excitations, the structure of the low lying levels in the lighter isotopes is dominated by the ${2f}_{7/2}$ neutron configuration.
