  Recent discovery of neutral bremsstrahlung (NBrS) mechanism of
electroluminescence (EL) in noble gases in two-phase detectors for dark matter
searches has led to a prediction that NBrS EL should be present in noble
liquids as well. A rigorous theory of NBrS EL in noble liquids was developed
accordingly in the framework of Cohen-Leckner and Atrazhev formalism. It has
been recently followed by the first experimental observation of NBrS EL in
liquid argon, which however deviates significantly from the previous theory.
Given these results, we revise previous theoretical calculations of EL NBrS in
noble liquids to be consistent with experiment. In particular, NBrS EL yield
and spectra were calculated in this work for argon, krypton and xenon with
momentum-transfer cross section of electron scattering (instead of
energy-transfer one) being used for calculation of NBrS cross section. The
results for light noble liquids, helium and neon, are also reexamined.
