Dear CCLers,

I wish to calculate LUMO and HOMOs for N-Allyl-O-Alkyl thiocarbamate 
molecules using an ab initio method. These are straight chain molecules 
containing C, O, N, H and C=C, C=S bonds with up to 12 atoms in 
the backbone.

Which  ab initio method should I use ?
Which basis sets ?

Thank you for your time.
