The influence of the admixture of the $^{3}F_{2}$ state onto collective spinoscillations and neutrino emission processes in the triplet superfluid neutronliquid is studied in the BCS approximation. The eigen mode of spin oscillationswith $\omega\simeq\sqrt{58/35}\Delta$ is predicted to exist in the tripletsuperfluid neutron condensate besides the already known mode$\omega\simeq\Delta/\sqrt{5}$. Excitation of the high-frequency spinoscillations in the condensate occurs through the tensor interactions betweenquasiparticles.  Neutrino energy losses through neutral weak currents are found to consist ofthree separate contributions caused by a recombination of broken Cooper pairsand by weak decays of the collective modes of spin oscillations. Neutrinodecays of the low-frequency spin waves can play an important role in thecooling scenario of neutron stars. Weak decays of the high-frequencyoscillations that occur only if the tensor forces are taken into account in thepairing interactions does not modify substantially the total energy losses.Simple expressions are suggested for the total neutrino emissivity.
