The H atoms were placed in geometrically idealized positions 
with C-H 
distances of 0.93\%A (aromatic),0.97\%A 
(idealized CH~2~) and 0.96\%A
(idealized CH~3~) and were
 constrained to ride on the parent C atom 
with Uiso(H) 
= 1.2Ueq(C) for the aromatic, CH~2~ and C-H protons and 
Uiso(H) 
= 1.5Ueq(C) for the idealized CH~3~ protons.
