Abstract
Conformations and inversion barriers of 5H-dibenzo[a,d]cycloheptene (1a), 5-amino-5H-dibenzo[a,d]cycloheptene (1b), 5-chloro-5H-dibenzo[a,d]cycloheptene (1e), 5-hydroxy-5H-dibenzo[a,d]cycloheptene (1d), 5-methyl-5H-dibenzo[a,d]cycloheptene (1f), N-benzyl-5H-dibenzo[a,d]cyclohepten-5-imine (2) and N-(5H-dibenzo[a,d]cyclohepten-5-yl)benzylideneamine (1c) have been studied by means of dynamic
