Summary : Ammonia clusters

Following message was written to CCL a week back & I received only two
 responses. Thanks a lot to those who responded promptly. I am waiting for more.
 The original post was:

 > using ab initio or any other theoretical/experimental methods?

     Hi!
 I am not sure but following refrences may help you
 in getting the necessay references on NH3 clusters.

 Some work, both experimental and semi-empirical, on protonated
 ammonia clusters (NH3)n(NH4)+ has been carried out in Jack
 Beauchamp's lab at CalTech. See:
