Tunnel frequency dependence of the i.-r. continuous absorption and the proton dispersion forces

Abstract

A continuous i.-r. absorption observed in solutions containing hydrogen bonds with symmetrical double minimum potential well may be due to tunnelling protons producing a fluctuating field causing attractive proton dispersion force. This decreases for tunnelling frequencies >5 × 10¹² s^–1 since the fluctuating dipole moment disappears. At lower frequencies it depends on electric dipole relaxation frequencies. For tunnelling frequencies below that of dielectric dispersion, the proton dispersion force again decreases rapidly.
