Abstract Cadmium is laser-cooled and trapped with excitations to triplet states with UVA light, first using only the 67 kHz wide 326 nm intercombination line and subsequently, for large loading rates, the 25 MHz wide 361 nm3P2→3D3transition. Eschewing the hard UV 229 nm1S0→1P1transition, only small magnetic fields gradients, less than 6 G cm−1, are required enabling a 100% transfer of atoms from the 361 nm trap to the 326 nm narrow-line trap. All 8 stable cadmium isotopes are straightforwardly trapped, including two nuclear-spin- fermions that require no additional repumping. We observe evidence of3P2collisions limiting the number of trapped metastable atoms, report isotope shifts for111Cd and113Cd of the 326 nm1S0→3P1, 480nm3P1→3S1, and 361 nm3P2→3D3transitions, and measure the114Cd 5s5p3P2→ 5s5d3D3transition frequency to be 830 096 573(15) MHz.

Snapshot of cyclooctyne ring-opening to a tethered alkylidene cyclic polymer catalyst
Cyclooctyne reacts with the trianionic pincer ligand supported alkylidyne [tBuOCO]WCC(CH3)3(THF)2(1) to yield tungstacyclopropene (3) and tungstacyclopentadiene (4) complexes.

Context.The methyl cation (CH3+) has recently been discovered in the interstellar medium through the detection of 7 μm (1400 cm−1) features toward the d203-506 protoplanetary disk by the JWST. Line-by-line spectroscopic assignments of these features, however, were unsuccessful due to complex intramolecular perturbations preventing a determination of the excitation and abundance of the species in that source. Aims.Comprehensive rovibrational assignments guided by theoretical and experimental laboratory techniques provide insight into the excitation mechanisms and chemistry of CH3+in d203-506. Methods.The rovibrational structure of CH3+was studied theoretically by a combination of coupled-cluster electronic structure theory and (quasi-)variational nuclear motion calculations. Two experimental techniques were used to confirm the rovibrational structure of CH3+:(1) infrared leak-out spectroscopy of the methyl cation, and (2) rotationally resolved photoelectron spectroscopy of the methyl radical (CH3). In (1), CH3+ions, produced by the electron impact dissociative ionization of methane, were injected into a 22-pole ion trap where they were probed by the pulses of infrared radiation from the FELIX free electron laser. In (2), neutral CH3, produced by CH3NO2pyrolysis in a molecular beam, was probed by pulsed-field ionization zero-kinetic-energy photoelectron spectroscopy. Results.The quantum chemical calculations performed in this study have enabled a comprehensive spectroscopic assignment of thev2+andv4+bands of CH3+detected by the JWST. The resulting spectroscopic constants and derived EinsteinAcoefficients fully reproduce both the infrared and photoelectron spectra and permit the rotational temperature of CH3+(T= 660 ± 80 K) in d203-506 to be derived. A beam-averaged column density of CH3+in this protoplanetary disk is also estimated.more » « less

Abstract The trichromium cluster (tbsL)Cr3(thf) ([tbsL]6−=[1,3,5‐C6H9(NC6H4‐o‐NSitBuMe2)3]6−) exhibits steric‐ and solvation‐controlled reactivity with organic azides to form three distinct products: reaction of (tbsL)Cr3(thf) with benzyl azide forms a symmetrized bridging imido complex (tbsL)Cr3(μ3‐NBn); reaction with mesityl azide in benzene affords a terminally bound imido complex (tbsL)Cr3(μ1‐NMes); whereas the reaction with mesityl azide in THF leads to terminal N‐atom excision from the azide to yield the nitride complex (tbsL)Cr3(μ3‐N). The reactivity of this complex demonstrates the ability of the cluster‐templating ligand to produce a well‐defined polynuclear transition metal cluster that can access distinct single‐site and cooperative reactivity controlled by either substrate steric demands or reaction media.more » « less

Abstract We report new measurements of branching fractions for 20 UV and blue lines in the spectrum of neutral silicon (Sii) originating in the 3s23p4s3Po1,2,1Po1, and 3s3p31Do1,2upper levels. Transitions studied include both strong, nearly pure LS multiplets as well as very weak spin-forbidden transitions connected to these upper levels. We also report a new branching fraction measurement of the4P1/2–2Po1/2,3/2intercombination lines in the spectrum of singly ionized silicon (Siii). The weak spin-forbidden lines of Siiand Siiiprovide a stringent test on recent theoretical calculations, to which we make comparison. The branching fractions from this study are combined with previously reported radiative lifetimes to yield transition probabilities and log(gf) values for these lines. We apply these new measurements to abundance determinations in five metal-poor stars.more » « less
