Abstract
This work describes experiments on thermal dynamics of pure H2O excited by hydrodynamic cavitation, which has been reported to facilitate the spin conversion of para- and ortho-isomers at water interfaces. Previous measurements by NMR and capillary methods of excited samples demonstrated changes of proton density by 12-15%, the surface tension up to 15.7%, which can be attributed to a non-equilibrium para-/ortho- ratio. Beside these changes, we also expect a variation of heat capacity. Experiments use a differential calorimetric approach with two devices: one with an active thermostat for diathermic measurements, another is fully passive for long-term measurements. Samples after excitation are degassed at -0.09MPa and thermally equalized in a water bath. Conducted attempts demonstrated changes in the heat capacity of experimental samples by 4.17%--5.72% measured in the transient dynamics within 60 min after excitation, which decreases to 2.08% in the steady-state dynamics 90-120 min after excitation. Additionally, we observed occurrence of thermal fluctuations at the level of 10^-3 C relative temperature on 20-40 min mesoscale dynamics and a long-term increase of such fluctuations in experimental samples. Obtained results are reproducible in both devices and are supported by previously published outcomes on four-photon scattering spectra in the range from -1.5 to 1.5 cm^-1 and electrochemical reactivity in CO2 and H2O2 pathways. Based on these results, we propose a hypothesis about ongoing spin conversion process on mesoscopic scales under weak influx of energy caused by thermal, EM or geomagnetic factors; this enables explaining electrochemical and thermal anomalies observed in long-term measurements.

这项工作描述了通过 hydrodynamic cavitation 刺激纯 H2O 的 thermal 动力学实验,据报道该方法有助于在水界面上促进对平行和Ortho 平行同分异构体的 spin 转换。过去通过核磁共振和毛细方法刺激样品的实验测量结果表明, Proton 密度发生了变化,表面张力上升到 15.7%,这些变化可能是由于非平衡的 para-/Ortho- 比例。除了这些变化,我们还期望热容量的变化。实验使用两个设备采用差分热膨胀方法:一个带有主动温度控制系统,另一个是完全 passive 的长期测量设备。刺激后样品在 -0.09MPa 温度下减压,并在温水浴中热平衡。进行的实验尝试表明,在 60 分钟内刺激后,实验样品的热容量发生了变化,从 4.17%-5.72% 测量到临时动态过程,而在 90-120 分钟内刺激后,该过程下降了到 2.08%。此外,我们还观察到在 20-40 分钟内mesoscale 动态过程中,存在 10^-3 C 相对温度的热波动,并观察到实验样品中此类波动的长期增加。这些结果支持了以前在 -1.5 到 1.5 cm^-1 范围内发表的四光子散射光谱和 CO2 和 H2O2 通道中的化学键反应性的结果。基于这些结果,我们提出了一个在受到 thermal、EM 或地球磁场因素较弱入侵的能量的作用下,在微观尺度上继续进行 spin 转换的假设;这有助于解释长期测量中观察到的化学和热异常。
