Structure in the Visible Absorption Bands of Jet-Cooled Phenylperoxy Radicals
The
visible absorption bands of the phenylperoxy radical in the
gas phase have been investigated using cavity ring-down spectroscopy.
Jet-cooling was used to reduce the spectral congestion. Structured
spectra spanning the range from 17 500 to 19 000 cm<sup>–1</sup> are reported for the first time. Analyses of these
data have been guided by the results from time-dependent density functional
calculations. The observed spectrum was found to be dominated by the
bands of the B̃<sup>2</sup>A″–X̃<sup>2</sup>A″ transition. An analysis of the rotational contour for the
origin band yielded a homogeneous line width of 2.2 cm<sup>–1</sup>, corresponding to a decay rate of 4.1 × 10<sup>11</sup> s<sup>–1</sup>. The results provide a rationale for the lack of
structure in room temperature spectra that have been previously attributed
to phenylperoxy. They also indicate that the lower energy region of
the spectrum may show resolvable structure at room temperature. If
so, this would provide a more definitive signature for monitoring
phenylperoxy in kinetic measurements
Sedimentological characteristics and new detrital zircon SHRIMP U–Pb ages of the Babulu Formation in the Fohorem area, Timor-Leste
<div><p>Sedimentological characteristics and zircon provenance dating of the Babulu Formation in the Fohorem area, Timor-Leste, provide new insights into depositional process, detailed sedimentary environment and the distribution of source rocks in the provenance. Detrital zircon sensitive high-resolution ion microprobe (SHRIMP) U–Pb ages range from Neoarchean to Triassic, with the main age pulses being Paleozoic to Triassic. In addition, the maximum deposition ages based on the youngest major age peak (<i>ca</i> 256–238 Ma) of zircon grains indicate that the basal sedimentation of the Babulu Formation occurred after the early Upper Triassic. The formation consists predominantly of mudstone with minor sandstone, limestone and conglomerate that were deposited in a deep marine environment. These deposits are composed of six lithofacies that can be grouped into three facies associations (FAs) based on the constituent lithofacies and bedding features: basin plain deposits (FA I), distal fringe lobe deposits (FA II) and medial to distal lobe deposits (FA III). The predominance of mudstone (FA I) together with intervening thin-bedded sandstones (FA II) suggest that the paleodepositional environment was a low energy setting with slightly basin-ward input of the distal part of the depositional lobes. Discrete and abrupt occurrences of thick-bedded sandstone (FA III) within the FA I mudstone suggests that sandstone originated from a collapse of upslope sediments rather than a progressive progradation of deltaic turbidites. This combined petrological and geochronological study demonstrates that the Babulu Formation in the Fohorem area of the Timor-Leste was initiated as a submarine lobe system in a relatively deep marine environment during the Upper Triassic and represents the extension of the Gondwana Sequence at the Australian margin.</p></div
