Even when considering the same general type of interaction (e.g., hydrogen bonding), these events must be understood in order to develop a system taking full advantage of the specific noncovalent interactions used. Figure 3 depicts two particularly well-established supramolecular motifs that utilize ...
This commentary focuses on the conceptual interpretation of the bonding of O2 and NO to heme in oxyheme and nitrosylheme complexes, using high-level ab initio complete active space self-consistent field (CASSCF)/molecular mechanical (MM), gas-phase CASSCF, and CASSCF followed by second-order ...

Identify which of the following molecules can exhibit hydrogen bonding as a pure liquid. For which of the following molecules would the intermolecular forces be influenced mainly by hydrogen bonding? CH3COCH3 O2 PH3 NO2 BF3 What is the maximum number of other molecules that can joined together ...
In order to form this full valence shell, the atom can either lose all of its current valence electrons or gain electrons until it has eight. Let's look at an example. Oxygen is in group 6, so it has six electrons in its outer shell. This means it either needs to gain two ...
Bonding in the ground state of C is still a matter of controversy, as reasonable arguments may be made for a dicarbon bond order of , , or . Here we report on photoelectron spectra of the C anion, measured at a range of wavelengths using a high-resolution photoelectron imaging spectrometer...

Such a tunability of chalcogen bonding can be used in the regulation of bond parameters as well as functional properties of materials, the ChB donor character of the Ch atom being expected to increase in the order O < S < Se < Te. For example, replacement of Se by the better ChB donor...
What intermolecular forces act between the molecules of O2? How are vapor pressure and intermolecular forces related? a) The stronger the intermolecular forces, the higher the vapor pressure. b) The weaker the intermolecular forces, the lower the vapor pressure. c) The stronger the intermolecular ...
