Emission from Water Vapor and Absorption from Other Gases at 5-7.5 Microns in Spitzer-IRS Spectra of Protoplanetary Disks [PDF]
, 2014 We present spectra of 13 T Tauri stars in the Taurus-Auriga star-forming region showing emission in Spitzer Space Telescope Infrared Spectrograph (IRS) 5-7.5 micron spectra from water vapor and absorption from other gases in these stars' protoplanetary ...

Isoprene emissions track the seasonal cycle of canopy temperature, not primary production: evidence from remote sensing [PDF]
Biogeosciences, 2014 Isoprene is important in atmospheric chemistry, but its seasonal emission pattern – especially in the tropics, where most isoprene is emitted – is incompletely understood.

Impact of Ventilation on Indoor Air Quality: Singular Behaviour of Formaldehyde
Chemical Engineering Transactions, 2019 Combined with material emission, ventilation has a direct impact on volatile organic compound (VOC) concentrations in indoor environments. In this work, the impact of ventilation on various VOC emission rates relative to wood particleboard is assessed ...

WSRT and VLA Observations of the 6 cm and 2 cm lines of H2CO in the direction of W 58 C1(ON3) and W 58 C2 [PDF]
, 2000 Absorption in the J{K-K+} = 2{11}-2{12} transition of formaldehyde at 2 cm towards the ultracompact HII regions C1 and C2 of W 58 has been observed with the VLA with an angular resolution of ~0.2'' and a velocity resolution of ~1 km/s.

Deuterated formaldehyde in rho Ophiuchi A [PDF]
, 2010 From mapping observations of H2CO, HDCO, and D2CO, we have determined how the degree of deuterium fractionation changes over the central 3'x3' region of rho Oph A.
