Abstract
Research within the area of selective energy transfer (SET) on how resonance develops between a specific vibration within a catalyst system and a corresponding vibration within a reacting system that resonates with it is discussed here. The catalyst system is assumed to donate one or more vibrational quanta to the reacting system. The term ‘specific vibration’ refers to vibration of a type involving bending or stretching that, when transferred resonantly to the reacting system, serves to drive the reactant molecules involved to assume the basic structure of the molecules of the catalyst system. Regardless of whether the catalyst is a pure metal surface or a complex polymolecular system (an enzyme), its role is seen to be that of transferring energy to corresponding vibrations of the reactant system. Examples are here presented of vibrators of various types that can act as catalysts.
Highlights
During the last few decades, work on developing and exploring a new conception of catalysis, selective energy transfer (SET), has been underway. This assumes there to be a resonant interplay between molecular vibrations of a catalyst and of a reactant, the vibrations of the reactant and of the catalyst being equal or nearly equal in frequency, and the reactions this involves being initiated when sufficient amounts of vibrational quanta from the catalyst have been transferred to the reactant-to-be
For the elements located in the middle of the lanthanide row, we found a finite value of 1/T to apply, which resulted in an isokinetic temperature of Tiso = 2500 ± 330 K
On the basis of what has been said above, one can conclude that the set of formulae that was presented in the first part of this paper fulfills its duty, so to speak
Summary
During the last few decades, work on developing and exploring a new conception of catalysis, selective energy transfer (SET), has been underway. The first of the two types of energy dissipation referred to above, which represents the usual conditions for heterogeneous catalysis, contains a large number of differing possibilities for the energy stored in the reactant molecule being lost. This problem can be resolved by integrating over all possible values of Q, from infinity to Q = 1/2, which results in Formula (3), taken from one of the early SET papers [2]. ∑∆Ei stands for the absolute value of the energy difference between one vibrational level (i + 1) and the one below it (i) It can be difficult in many cases to ascertain the reaction rate in absolute terms. Leading towards SET, are presented to the reader [5,6,7,8,9,10,11,12,13,14,15,16,17]
