7. The dependence of chain scission and racemization on temperature results from molecular motion, "cage effect" and steric hindrance during recombination.
分子量降低和消旋作用对温度的依赖性，是由于分子运动和笼罩效应以及重合的空间位阻效应所致。

8. The rate constant of racemization of L-Pro increased with decreasing acidity of the carboxylic acid. However, the racemization of L-His was most rapid in acetic acid.
消旋速率因羧酸溶剂的不同而异：L-组氨酸在乙酸溶剂中消旋最快，而L-脯氨酸在正丁酸溶剂中最快。

9. By the way, if you're curious about why racemization is so much less accurate a clock than C-14 for dating a tooth's age, part of the explanation has to do with temperature.
10. However, when the researchers applied both techniques to teeth, they realized that the racemization offered an additional useful detail, a good gauge of an individual's age at death.
11. By analyzing how much racemization of its aspartic acid occurred, scientists can determine how old the tooth's owner was at death - generally accurate to about 5.5 years, plus or minus 4.2 years.
