Higher-than-binary complexes

Intermolecular forces are repulsive at close range (R < Kmm) and attractive at distant range (R > Rmj Rm n is the position of the minimum of the pair interaction potential). At high enough densities most of the common gases form dimers, also called double molecules or (binary) van der Waals molecules. Higher than binary complexes are expected, too, especially at high densities and temperatures comparable to, or lower than the well... 

Additionally, we speculated that the lowest OH internal excitations (i.e., v = 0, low N) might derive preferentially from higher-than-binary complexes and/or a mechanism that involves a five-atom HO(Br)CO intermediate produced by a multicenter process following photoexcitation (Hoffmann et al. 1990). 

The observed differences in the OH buildup rates at a given photolysis wavelength can be attributed to OH rotational levels having different parentages. For example, if higher-than-binary complexes yield mainly low N, this could be reflected in the product-state-selective measurements, even if the number of higher complexes is smaller than the number of binary complexes. In this case, there would be differences between results obtained with product state resolution versus those obtained by using a broadband probe. The latter would only be sensitive to the low N contribution in direct proportion to its fraction of the total product... 

The case of higher-than-binary complexes is harder to deal with. Such complexes are almost certainly present to some extent under the experimental conditions used in our work, but it is hard to quantify their contributions. For example, they could contribute to the relatively cold components of the OH rotational distributions observed in our measurements, This point remains to be settled quantitatively. 

ABC terblock copolymers in confined geometries exhibit a higher versatility and complexity of phase behavior than do binary block copolymers, and this has only been partly explored so far [4, 18, 63],... 

Agonists bind with higher affinity to the ternary complex than to the binary complex and in addition, stabilize and promote the formation of the ternary complex. The coexistence of these binary and ternary complexes in the membrane provide a molecular basis for the characteristic biphasic, shallow curve of agonist...
