I am organizing a one-day program in the 15th ACC(Asia Congress on Chem, 2013, Singapore) on the theme of “Water Science Engineering” with 4 possible sessions: 1. Water Chemistry Physics 2. Water Purification 3. Water Splitt ...
1. 在零度附近,实键服从常规热胀冷缩规则;而虚键则相反;导致冰的反常体膨胀; 2。 结冰时,由于虚键极化和实键电子屏蔽,实键声子软化而虚键声子硬化; 3。 对过冷水,键长和声子频率变化情况恰好相反。 The melting temperature T m of ice I h was determined as 411 ...
1实键高频拉曼模式发生红移;而虚键低频拉曼模式发生蓝移; 2初步研究表明:高压使冰的虚键变短而强使实键变长而弱;理论期盼与计算和实测一致; 3深入研究正在进行,待续。。。 Hydrogen bond relaxation dynamics and the associated anamolies of frozen H2O upon compression http: ...
