TL;DR: In this article, the gas-phase E.P.R. spectra of the OH in the J = 9/2 and 11/2 levels of the X2II state at 26 GHz and 35 GHz respectively are reported.
Abstract: Measurements of the gas-phase E.P.R. spectra of OH in the J = 9/2 and 11/2 levels of the X2II state at 26 GHz and 35 GHz respectively are reported. Confocal and semi-confocal optical resonators have been used in place of the more conventional microwave cavities for these experiments. The data are analysed, together with previous measurements by Radford on other rotational levels in the determination of six independent g factors: These parameters are interpreted in terms of the electronic structure of the OH radical. In agreement with previous workers, it is found that the major contaminant of the X2II state is the A2Σ+ state and that this pair of states is a good example of Van Vleck's pure precession hypothesis.

TL;DR: In this paper, thin films of titanium dioxide (TiO2) were deposited on a variety of substrates by a simple sol-gel dip coating technique, where the substrates were coated with titanium peroxide precursor solution of controlled viscosity at a constant pulling rate of 1mm s−1, air-dried and further heated at 400°C to obtain uniform films with good adhesion to the substrate.

TL;DR: This Account uncovered a transition-metal-free protocol for the synthesis of 9,10-dihydrophenanthrenes by the reaction of arynes with styrenes that proceeds via a Diels-Alder/ene-reaction cascade and disclosed aryne MCCs initiated by N-heterocycles such as (iso)quinoline, pyridine, and aziridines.
Abstract: ConspectusArynes are highly reactive intermediates having several applications in organic synthesis for the construction of various ortho-disubstituted arenes. Traditionally, arynes are generated in solution from haloarenes under strongly basic conditions. However, the scopes of many of the aryne reactions are limited because of the harsh conditions used for their generation. The renaissance of interest in aryne chemistry is mainly due to the mild conditions for their generation by the fluoride-induced 1,2-elimination of 2-(trimethylsilyl)aryl triflates. This Account is focused on the Diels–Alder reaction of arynes and their transition-metal-free application in multicomponent couplings as well as arylation reactions.The Diels–Alder reaction of arynes is a powerful tool for constructing benzo-fused carbocycles and heterocycles. In 2012, we developed an efficient, broad-scope, and scalable Diels–Alder reaction of pentafulvenes with arynes affording benzonorbornadiene derivatives. Subsequently, we accomplish...

TL;DR: In this article, a wall jet electrode was presented, in which a jet of solution issued from a circular nozzle was allowed to impinge normally on a disk electrode. And the theoretical predictions for the dependence of the limiting diffusion current upon various experimental variables, i.e., the bulk concentration of depolarizer, the volume flow rate, the radius of the disk electrode, the diameter of the nozzle, etc., were verified experimentally.

TL;DR: In this article, a screen printed thick-film H2, CO and CH4 gas sensors were fabricated on an alumina substrate by mixing ZnO with lead borosilicate glass frits as a binder and Sb as a catalyst.
