TL;DR: The spectral evidence tentatively suggests a monodentate hydrogen bond for the (CF 2 H) 2 O•F − complex, rather than the bidentate structure inferred from ion cyclotron resonance data as discussed by the authors.

TL;DR: In this paper, the matrix isolation technique has been combined with infrared spectroscopy to characterize the interaction between Cp 2 TiF 2 and Cp2 TiCl 2, and HCl.
Abstract: The matrix isolation technique has been combined with infrared spectroscopy to characterize the interaction between Cp 2 TiF 2 and Cp 2 TiCl 2 , and HCl. Isolated 1/1 complexes were observed for each pair of reactants; the Cp 2 TiF 2 .HCl complex was characterized by a red shift of the HCl stretching mode to 2440 cm -1 and a dramatic broadening of this absorption. In addition, strongly perturbed Ti-F stretching modes were observed near 536 and 556 cm -1

TL;DR: In this article, the products of the reaction of oxygen atoms with propene were investigated following the excimer-laser-induced photodissociation of N 2 O or O 2 in argon matrices at 14 K.
Abstract: The products of the reaction of oxygen atoms with propene were investigated following the excimer-laser-induced photodissociation of N 2 O or O 2 in argon matrices at 14 K. The system was complicated by the photodissociation of propene itself at 193 nm, and the possibility of the reaction of the fragmentation products with the oxygen atoms. In the N 2 O—propene experiments, acetone was observed as the major product, with propanal and methyloxirane barely detectable as minor products. In the O 2 —propene experiments, propanal was the major product, although the overall yields were low. These results are consistent with earlier gas phase studies, and suggest that the electronic state of the photogenerated oxygen atom is important in determining the course of the reaction.
