举例说明,如果你面前有一瓶水,那么里面一个水分子(H2O)里氢原子和氧原子之间为intramolecular,根据它们的electronegativity difference, 该是polar covalent bond。每一个水分子(也就是说每个H2O为一个单独整体)之间的关系是intermolecular。 P.S. 如果你想到hydrogen bond,那就是混淆了!Hydrogen bond属于intermolecular b...
In contrast, its chemical analogue is a bimolecular reaction, and corresponds to the intermolecular disulfide interchange between a mixed disulfide-bonded compound between a cysteine residue and glutathione, and a free cysteine molecule. The difference in the intrinsic free energy of the above two ...
The paper discusses the role of weak intra- and intermolecular hydrogen bonds in the adsorption of benzyl alcohol, 2-phenylethanol and 2-phenylethylamine on graphitized thermal carbon black (GTCB). Using the B3LYP/aug-cc-pVDZ, B3LYP/aug-cc-pVTZ methods and the molecular-statistical theory of ads...
What type(s) of intermolecular forces is/are expected between 3-bromopyridine molecules? What types of intermolecular forces exist between HCl molecules? What is the difference between intermolecular and intramolecular forces? What intermolecular forces are present in the molecule FN...

Full size image Results Synthesis of crystalline polycarbonates from 3,5-dioxaepoxide For the alternating copolymerization of CO2withmeso-epoxides mediated byracemicisotactic...
L. Role of intramolecular and intermolecular hydrogen bonding in both singlet and triplet excited states of aminofluorenones on internal conversion, intersystem crossing, and twisted intramolecular charge transfer. J. Phys. Chem. A 113, 14329–14335 (2009). 30. Menning, S. et al. Bridged to...
the proteins of the photoreceptor undergo two contemporaneous different phenomena: an intramolecular switch, i.e., the proteins undergo isomer interconversion, A498 becomes B462, and an intermolecular and unidirectional Forster-type energy transfer, i.e., the newly formed B462 acts as a donor for...
Rayleigh wing and Fourier transform infrared studies of intermolecular and intramolecular hydrogen bonds in liquid ethylene glycol Depolarized low frequency light scattering and infrared data for ethylene glycol are presented. The measurements, performed in the temperature range 7160 ... V. CRUPI,M. P....
(t) can be described as the sum of the above convoluted function and one error functionE(t) to take into account the difference of baseline between the positive and the negative delay regions. The width of the error function is fixed to the one ofg(t). The explicit forms ofF(t),g(...
Next, we determined the NMR structure of the complex (Fig.3Aand Supplementary Table4) by the combination of the RDC data for PRPF40A and NOE-derived distance restraints, including 261 intermolecular NOEs (Supplementary Fig.10), from complementary labeling schemes (13C,15N labeled PRPF40A and un...
