The energy levels, oscillator strengths, radiative decay rates, lifetimes, collision strengths, direct and resonance electron-impact excitation rate coefficients have been computed for the 257 fine-structure levels arising from $1s^{2}2s^{2}2p^{5}nl$ and $1s^{2}2s2p^6{n}^{\prime }{l}^{\prime }$ configurations belonging to the $M{o}^{32+}$ ion with $n\le 7$, $l\le 4$ and $n^{\prime }\le 5$, $l^{\prime }\le 4$. The model-potential approach is used for the target ion structure calculations. Additionally, we employ the multiconfiguration Dirac–Hartree–Fock method to further assess the energy levels and transition probabilities. The collision strengths for the electron-impact direct excitation are computed within the relativistic distorted-wave approximation at 34, 135, 680, 1700, 5436, and 12,740 eV scattered electron energy values. We also perform collision calculations at 85, 175, and 450 keV electron energies using the plane-wave approximation and interpolate the reduced cross section within Fano plots, thus accounting for relativistic effects at asymptotic energies. This assures the convergence of Maxwellian integration for effective collision strengths calculation at electron temperatures up to $80$ keV. The resonance contribution to the excitation rates is accounted for within the independent process isolated resonance approximation by including Na-like $M{o}^{31+}$ doubly excited autoionization states arising from the $1s^2{2}^{7}nl{n}^{\prime }{l}^{\prime }$ configurations with $n\le 7,l\le 4,n^{\prime }\le 20,l^{\prime }\le 8$. Contributions from high $n^{\prime }\ge 21$ Rydberg states to the excitation rate coefficients are included by employing the ${n{}^{\prime }}^{-3}$ extrapolation law for radiative and autoionization decay rates. Radiative decay of resonances to lower autoionization states followed by autoionization cascade as well as radiative damping via core transitions are included in our model. The highest rate coefficients corresponding to ground state excitations are the $2p$–$3d$ allowed and $2p$–$3p$ electric monopole transitions, respectively. Intercombination and generally higher-order electric multipole transitions amount to lower excitation rate coefficients but are not to be neglected. Magnetic transitions are only relevant for low electron temperatures since both their direct and resonance contributions to excitation significantly decrease with increasing electron energy. Present results compare well with existing data from literature. The resonance contributions play an important role in the accuracy of rate coefficients, especially for weak forbidden transitions at low electron temperatures. These results may be useful in fusion related plasmas, astrophysics and fundamental physics.
