Two intramolecular hydrogen bond O(5)-H(5)***O(6) and O(7)-H(7)***O(6) are formed in a molecule (Table-2).
Interactions are regulated across a wide variation of length scales and time scales from molecular and intramolecular interactions, all the way up to interactions between animals or between ecosystems.
This discrepancy is potentially explained by the ENE groups on the POSS cage reacting with each other (intramolecular), rather than functioning as a coagent with the HNBR (intermolecular) (figure 2).
The condensation reaction of these groups was essentially part of the intramolecular transesterification process.
Various parameters were determined including the equilibrium adsorption capacity of the adsorbent, the pH, conductivity, molecular activation energy, and the relative changes in the intramolecular energy and proportion of free water.
The higher viscosifying ability [1] and lower molecular surface activity [2] of polymers are mainly induced by the intramolecular association and intermolecular association generated by weak intermolecular forces, such as hydrophobic interaction of hydrophobic groups in aqueous solutions [3].
O intramolecular hydrogen bond may be considered a descriptor of HB strength.
However, the appropriate substitution, electron donor-acceptor- (D-A-) type structure on the pi-backbone, induces intramolecular charge transfer (ICT) accompanied with the quantum yield increment and the red shift of the fluorescence emission wavelength (see the absorption and emission wavelengths with quantum yield information in Figure 2) [8, 9].
As shown in Figure 1, juglone and its derivatives possess an intramolecular hydrogen bond between hydroxyl and keto groups.
