Carboxylic acid–aldehyde complexesBinding energyOxygenated organic compoundsCluster formationCarboxylic acids have been recognized as important precursor species in atmospheric new particle formation. To clearly understand how aerosols form at the molecular level we investigated the hydrogen bonding interactions ...
Far infrared studies of hydrogen bonding in carboxylic acids—I formic and acetic acids The three infrared active hydrogen bond vibrations of the cyclic dimer of formic acid have been reassigned, with the modes of vibration verified by normal coordinate analysis of the deuterated species. For acetic...
Building bridges: Carboxylic acid functionalization of anthradithiophenes (ADT) affects ordering in thin films via hydrogen bonding. The extended network of hydrogen bonds in the diacid ADT allows for fast and efficient triplet formation and long﹍ived, effective triplet separation. The monoacid ADT ...
Hydrogen bonding between carboxylic acid and amide groups was demonstrated for a series of amides called [n]-semirubins consisting of a dipyrrinone attached to the end of an n-carbon alkanoic acid. Such hydrogen bonding is more effective than the alternative amide to amide or acid to acid ...
(iii) Electrophilic substiution in benzoic acid takes place at the meta position. View Solution Why do alcohols have higher boiling points than haloalkanes of the same molecular mass? View Solution The high boiling points of carboxylic acids are due to ...
different from the spectra of the electrostatic O—HX hydrogen bonds in the other choline halides; however, this spectrum cannot be accounted for in terms of a "very strong" covalent O H F bond such as those found in carboxylic acid—fluoride ion complexes or postulated for betaine hydro...
Crystalline porous molecular frameworks formed through intermolecular hydrogen bonding are often called hydrogen-bonded organic frameworks (HOFs) by analogy to metal organic frameworks (MOFs) and covalent organic frameworks (COFs). Although the origin ma
the lactam ring and two hexanoic acid groups (one at C(9), the other at C(8) of the pyrrole ring) was synthesized to determine its ability to form intramolecular hydrogen bonds to the lactam unit from either carboxylic acid, whether in the syn -( Z ) or anti -( Z ) conformation. ...
In this work we demonstrate that a doubly hydrogen-bonded interface of two carboxylic acid groups behaves as efficient conduit to transmit the rotor effect... CK Nandi,MK Hazra,T Chakraborty - 《Journal of Chemical Physics》 被引量: 15发表: 2004年 Ammonium salts of benzoic acid and the cryst...
bonding stability can be achieved when there is formation of multiple hydrogen bonds between two such systems and elicits a response. Because of the presence of amino acid residues in receptors containing both the hydrogen bond donor and acceptor functionalities, hydrogen bonding plays a crucial role...
