I read with interest your article on targeting drugs (New Scientist,
Science, 7 December 1996, p 22), where you state that a pi-facial bond has an
energy of 4.5 kilojoules. If you had an ounce of this stuff, combining it would
release about 1026 joules, or 1019 times as much as that released during
uranium fission, weight for weight.
The article should, in fact, have said 4.5 kilojoules per mole—Ed
