On page 2073 , Pradeep R. Varadwaj, Arpita Varadwaj, and Gilles H. Peslherbe present an electronic structure theory investigation of the physical chemistry of intermolecular complexes of cyclopropenylidene with hydrogen halides. The image shows a relief map of the Laplacian of the electron density showing marked maxima at various nuclear positions of the c‐C 3 H 2 …H—Br complex. It shows the delocalization of the H—Br proton between the c‐C 3 H 2 carbene center and the Br − ion as well as the carbene electron density shift towards the shared proton, thus leading to a large amount of proton transfer along the hydrogen bond upon the formation of the c‐C 3 H 2 …H—Br complex.
