Vibrationally resolved transition state spectroscopy of the F + H2 and F + CH4 reactions
Faraday Discuss., 157, 399.
Contributors: T. Yacovitch *, E. Garand *, J. Kim *, C. Hock*, T. Theis* & D. Neumark *
TL;DR:
SEVI spectra of the 2P3/2 bands of FCH4- and FCD4- show extended structure from transitions to the entrance valley van der Waals region and the reactant side of the F + CH4 transition state region, attributed to bending or hindered rotation of the methane moiety and may be a spectroscopic signature of reactive resonances.

Zero-Field NMR Enhanced by Parahydrogen in Reversible Exchange
J. Am. Chem. Soc., 134(9), 3987–3990.
Contributors: T. Theis* , M. Ledbetter*, G. Kervern *, J. Blanchard *, P. Ganssle*, M. Butler *, H. Shin*, D. Budker *, A. Pines *
MeSH headings : Hydrogen / chemistry; Magnetic Resonance Spectroscopy; Pyridines / analysis
TL;DR:
Because the NH-PHIP mechanism is nonreactive, operates in situ, and eliminates the need for a prepolarizing magnet, its combination with optical atomic magnetometry will greatly broaden the analytical capabilities of zero-field and low-field NMR.
