  The process of neutrino interaction with $^{98}$Mo and $^{100}$Mo isotopes is
studied taking into consideration the effect of charge-exchange resonances. The
experimental data on the strength functions $S(E)$ obtained in charge-exchange
reactions $(p; n)$ and $(^3\mathrm{He}, t)$ and the strength functions $S(E)$
calculated within the theory of finite Fermi systems were used. We studied the
effect of the resonance structure of $S(E)$ on the cross sections for
solar-neutrino. We investigated the contribution of each high-lying resonance
to the capture cross section $\sigma(E_{\nu})$. The contributions of all
components of the solar neutrino spectrum are calculated. We estimate the
contribution of different components of solar neutrinos as the background for
the double-beta decay experiments on $^{100}$Mo.
