(color online) Convolved and spherically averaged momentum distributions of glycine. Boltzmann weighted contributions of Ip (53%), IIn (24%), IVn (14.7%), and IIIp (8%) conformer are given. Theoretical sum1 is the scaled sum of the individual distribution for four structures (Ip, IIn, IVn, and IIIp) according to relative Boltzmann populations at 438 K and IIIp conformer is not included in sum 2. Solid dots are the EMS experimental data, cited from Ref. [12].
