Infrared Measurement of Fluorocarbons, Carbon Tetrachloride, Carbonyl Sulfide, And Other Atmospheric Trace Gases

Role of Microorganisms in the Atmospheric Sulfur Cycle

“…As shown in Table XIX, Singh (1977) has recently detected SFs in air, but S02F2 has not thus far been detected.

The ultraviolet spectrum of OCS from first principles: Electronic transitions, vibrational structure and temperature dependence

“…Two of the triplet states are repulsive and the other two are bound in the inner region. In what follows, the states 1 1 A , 2 1 A , 1 1 A , and 2 1 A will be referred to as X, A, B, and C, respectively, and the triplet states 1 3 A , 1 3 A , 2 3 A , and 2 3 A will be termed a, b, c, and d (see Table I). …”

“…1 The atmospheric mixing ratio of OCS has increased from between 0.3 and 0.4 ppb (parts-per-billion, i.e., nmol mol −1 ) in pre-industrial times to about 0.5 ppb today; it is the most abundant sulfur containing compound in the atmosphere. 2,3 Its sources include direct and indirect emission from the ocean and various anthropogenic sources including fuel combustion and coal gasification.…”

The oceanic cycle and global atmospheric budget of carbonyl sulfide

“…Since COS was first measured in the troposphere in the 1970's (Hanst et al, 1975) and an average concentration of around 500 parts per trillion by volume (pptv) was revealed (Sandalls and Penkett, 1977), efforts were made to understand the spatial and temporal trends of this important gas. The first extensive data set of COS from a wide latitudinal range (57"s to 70°N) over the Pacific Ocean was published by Torres et al (1980).…”

“…SO, and H,S had been proposed by Junge (1974) to be possible transporters of sulfur from the troposphere, but on the basis of their fast removal times, Crutzen (1976) discounted this possibility. COS was discovered in tropospheric air by Hanst et al (1975), and was first measured in the stratosphere by Inn et al (1979). Both Crutzen…”
