Very Cool Chemistry
Fundamentals: Reactions at nano-Kelvin temperatures illustrate the role of
quantum mechanics in reactivity
Jyllian Kemsley
The first indication that chemical reactions can occur at nano-Kelvin
temperatures has raised the tantalizing possibility of a new realm of
quantum-controlled, ultracold chemistry (Science 2010, 327, 853).
“Being able to carry out chemical reactions at virtually absolute zero is a
completely new regime fo | b*******g 发帖数: 1309 | | S******G 发帖数: 965 | 3 quote
" In that situation the molecules are barely mobile and won’t react because
the Pauli principle forbids them from interacting. When the researchers
flipped the orientation of the nuclear spins of some molecules so the waves
of the molecules could overlap, however, pairs of KRb molecules
with different nuclear spins reacted to produce K2 and Rb2, even when the
original molecules were as far as 1 μm apart."
介个是成功率是100%的有效碰撞。
打个比方,没有互联网之前两地没法谈恋爱,因为彼此的信息接受不到,你也不知道对
方是不是异性呢。所以只有自己找老妈寻同事介绍。现在通过网
