We present laboratory rotational spectroscopy of five isomers cyanoindene (2-, 4-, 5-, 6-, and 7-cyanoindene) using a cavity Fourier-transform microwave spectrometer operating between 6-40 GHz. Based on these measurements, we report the detection 2-cyanoindene (1H-indene-2-carbonitrile; 2-C$_9$H$_7$CN) in GOTHAM line survey observations dark molecular cloud TMC-1 Green Bank Telescope at centimeter wavelengths. Using combination Markov Chain Monte Carlo (MCMC), spectral stacking, matched...
We have conducted an extensive search for nitrogen-, oxygen-, and sulfur-bearing heterocycles toward Taurus Molecular Cloud 1 (TMC-1) using the deep, broadband centimeter-wavelength spectral line survey of region from GOTHAM large project on Green Bank Telescope. Despite their ubiquity in terrestrial chemistry, confirmed presence a number cyclic polycyclic hydrocarbon species source, we find no evidence any heterocyclic species. Here, report derived upper limits column densities these...
Abstract Utilizing low‐frequency events reported by the Marsquake Service (MQS), we selected waveform data collected from InSight mission to characterize origins of three potential marsquakes. S0173a and S0235b were determined originate near Cerberus Fossae region. Our calculated backazimuths epicentral distances in agreement with those provided team. The third event, S0325ab, likely originated southeast lander an distance 38.4°, uniquely placing it boundary between Martian highlands...
ABSTRACT Two closely related isomeric pairs of cyanides, CH3[CN/NC] and H2C[CN/NC], are studied in cold, dark interstellar cloud conditions. In contrast to the diverse detections methyl cyanide (CH3CN) space, isocyanide (CH3NC) has previously only been observed warm hot star-forming regions. We report detection CH3NC cold pre-stellar core Taurus Molecular Cloud (TMC-1) using Green Bank Telescope with a significance 13.4σ. Hyperfine transitions H2CCN quadrupole interactions CH3CN were matched...

To date, most research regarding amino acid detection and quantification in fingermarks relies on spectrometric methods. Herein, the Sakaguchi colorimetric test was adapted to a rotationally-driven microfluidic platform used detect quantify arginine deposited by male female donors. A red color indicates presence of given sample following reaction, intensity this is linearly proportional concentration. Objective were accomplished using image analysis software (freeware) based result. The mean...
