|Issue Date:||14-Feb-2013||Citation:||Han, G., Thirunahari, S., Shan Chow, P., Tan, R.B.H. (2013-02-14). Resolving the longstanding riddle of pH-dependent outcome of glycine polymorphic nucleation. CrystEngComm 15 (6) : 1218-1224. ScholarBank@NUS Repository.||Abstract:||We have experimentally studied the nucleation of acidic and basic glycine aqueous solutions using in situ Raman spectroscopy and hence resolved the longstanding riddle of pH-dependent polymorphic outcome. We have found that typical inorganic acids and bases accelerate the nucleation rates of both α- and γ-glycine, with γ-glycine promoted to a greater extent hence formed preferentially over α-glycine. We hypothesize that glycine ions, readily formed in an acidic or basic environment, induce head-to-tail molecular ordering which structurally matches γ-glycine and primarily directs nucleation path from α-glycine to γ-glycine. © 2013 The Royal Society of Chemistry.||Source Title:||CrystEngComm||URI:||http://scholarbank.nus.edu.sg/handle/10635/64519||ISSN:||14668033|
