charge trans·fer com·plex

1. a complex between two organic molecules in which an electron from one (the donor) is transferred to the other (the acceptor); subsequent transfer of a hydrogen atom completes the reduction of the acceptor; such complexes are generally highly colored and may be so observed;
2. a network of hydrogen bridges at the catalytic center of certain proteases.

Therefore, it is of much importance and interesting to study the charge transfer complexes of drugs with various I or I-acceptors for qualitative and quantitative analysis of drugs in their pure form as well as in pharmaceutical formulations[15].
Performing fitting of the Nyquist curves in Figure 4, the ohmic resistance, charge transfer internal resistance and diffusion resistance of the cell at different SOC were obtained, as shown in Figure 5.
With a resistance at the Schottky barrier less than silicon resistance, charge transfer occurs over the metal, then the charges move in the silicon layer to the next filled track, and the process is repeated in the same way further, leading to a decrease in the system impedance.
For Mo[S.sub.2], both the charge transfer and interface dipole interaction are much weaker compared with graphene and hBN, respectively.
Ti[O.sub.1.04] with charge transfer mechanism could perform better than Ti[O.sub.2] in the SERS detection.
The charge transfer between cation pairs is unlikely to take place in the color-induced cations of the sole Y site, and the color of tourmaline is probably induced from the absorption of the d-d transition of transition metals in the crystal structure instead.
All the positive values of q imply that the charge transfers from the gas molecules to the Ti[O.sub.2] surface, suggesting that the gas molecules perform as the electron donor while the Ti[O.sub.2] surface as the electron acceptor.

It's easier in two-stroke form as the cylinder head has to accommodate the smaller cylinders so there is little space for valves, and it's 'turblown' as it doesn't use the crank-case for air charge transfer, thus avoiding oil carryover and contamination.
This results in red-shifted and well separated charge transfer peak from the main [pi],[[pi].sup.*] band.
A continuous damage evolution mechanism was proposed which contains the following three stages: (I) mass transport within the coating and the corrosion porous layer, (If) mass transport and charge transfer mechanism mixture due to the formation of active sites beneath the coating layer, and (III) charge transfer dominant mechanism due to adsorption and electrochemical reaction.
