Thank you. This is exactly the context in which the question came up.
Our lecturer listed:
Graphite sp2
Amorphous carbon (soot) sp2 (some sp3)
Diamond sp3
and we said 'What about sp3 (some sp2)?'
and he said 'Ah! That's amorphous diamond'
Which as you say, sounds like a contradiction in terms.
Thanks also to antoni s gozdz and all who have mailed me; this undergrad's
curiosity is satisfied (for now!).
