Electrical Co-operative Effects in Crystalline Long-Chain Secondary Alcohols


IT has been shown1 that, in polar solids, short-range forces may cause a very high energy difference V between equilibrium positions of the dipoles, and, at temperatures where kTV, dielectric absorption of the Debye type may be negligible. Experimental results2 show that this theory applies to several crystalline long-chain ketones at room temperature. Although these compounds gave negligible absorption at radio frequencies, high dielectric loss was observed at low frequencies (50–1,000 c./s.), the loss angle increasing, in each case, with decreasing frequency and with decreasing chain-length of the molecules. This absorption was considered to be due to short-range interaction, which causes the dipoles to reverse their direction in groups. Such interaction has been shown theoretically to lead to enhanced polarization3 and absorption, and to shift the absorption peak to lower frequencies4.
