Thermoluminescence of homeopathically prepared ultra-high dilutions of lithium chloride in deuterium oxide (D2O) (10 (-30) g cm (-3); C15 LiCl in D2O) and similarly prepared D2O (C15 D2O) was compared in three experiments varying (1) time between preparation of substance and time of experimentation, and (2) time between irradiation and thermoluminescence recording. Data were also compared with a normal solution 0.1 M LiCl in D2O and with pure D2O.
To record thermoluminescence, the solutions were frozen in liquid nitrogen (77 K, -196 degrees C), irradiated with 1 kGy, and after a succession of definite storage periods, were progressively rewarmed to 238 K (-35 degrees C).
Thermoluminescence patterns of C15 LiCl in D2O, C15 D2O, and D2O were similar. The average thermoluminescence intensity of C15 LiCl in D2O tended to be less than C15 D2O when tests were performed shortly after preparation of the substances and with short storage time between irradiation and recording of thermoluminescence. Thermoluminescence of D2O was significantly lower than from C15 D2O, particularly when the time between irradiation and recording was increased.
The nature of the phenomena here described still remains unexplained. Nevertheless, data suggest that thermoluminescence might be developed into a promising tool to study homeopathically prepared ultra- high dilutions.

    ABSTRACT: Homeopathic remedies are produced by potentising, that is, the serial logarithmic dilution and succussion of a mother tincture. Techniques like ultraviolet spectroscopy, nuclear magnetic resonance, calorimetry, or thermoluminescence have been used to investigate their physical properties. In this study, homeopathic centesimal (c) potencies (6c to 30c) of copper sulfate, Hypericum perforatum, and sulfur as well as succussed water controls were prepared. Samples of these preparations were exposed to external physical factors like heat, pressure, ultraviolet radiation, or electromagnetic fields to mimic possible everyday storage conditions. The median transmissions from 190 nm to 340 nm and 220 nm to 340 nm were determined by ultraviolet light spectroscopy on five measurement days distributed over several months. Transmissions of controls and potencies of sulfur differed significantly on two of five measurement days and after exposure to physical factors. Transmissions of potencies exposed to ultraviolet light and unexposed potencies of copper sulfate and Hypericum perforatum differed significantly. Potency levels 6c to 30c were also compared, and wavelike patterns of higher and lower transmissions were found. The Kruskal-Wallis test yielded significant differences for the potency levels of all three substances. Aiming at understanding the physical properties of homeopathic preparations, this study confirmed and expanded the findings of previous studies.
