CCL: Barrierless channel



 Sent to CCL by: "Benoit  Gearald" [ablux13(a)gmail.com]
 Dear CCLers,
 I'm studying a multichannel reaction. I've found a barrierless channel i.e.
 the transition state is below the intermediate and I have confirmed that by
 different methods of calculation.
 My question is whether I have to locate a molecular complex that links the
 intermediate to the TS or it's ok as it is?
 I'm really confused on that point and need some explanations and
 clarifications.
 Best regards,
 Benoit
