Comparison of the Recoil Reactions in the 80mBr-CH4 and 82mBr-CH4 Systems [PDF]
Bulletin of the Chemical Society of Japan, 1970 Abstract The reactions of 80Br and 82Br excited by the isomeric transition processes with CH4 have been compared with each other. Similar reaction processes; energetic and thermal ionic, are involved in both cases. However, the isotope effect appears in the energetic process to form CH3Br, but not in the thermal ionic process to form ...

Journal de Physique, 1977 Les échanges collisionnels d'énergie entre les deux premiers niveaux (ν 2, ν4) de vibration de CH4 et les degrés de translation-rotation sont étudiés expérimentalement par la méthode du spectrophone. Le montage expérimental est décrit et les constantes de vitesse vibration-translation des niveaux ν2, ν 4 sont déterminées pour les collisions CH4-CH4 et ...

PLoS ONE, 2017 Although estimates of the annual methane (CH4) flux from agriculturally managed peatlands exist, knowledge of controls over the variation of CH4 at different time-scales is limited due to the lack of high temporal-resolution data.

Decomposition of CO2, CH4 and CO2-CH4 mixed gas hydrates.
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1997 To evaluate the possibility of CH4 exploitation in linkage with CO2 isolation, the decomposition rates of CO2, CH4 and CO2-CH4 mixed gas hydrates were obtained under isothermal isobaric conditions. The decomposition rates of CO2 and CH4 pure gas hydrates are proportional to the total amount of gas hydrate and the fugacity difference from the ...

Large methane oxidation across an oxygen gradient in Baltic Sea deep waters
Limnology and Oceanography LettersRobust estimations of methane (CH4) oxidation in marginal seas remain elusive, making CH4 budgets particularly uncertain. Here, we investigate the CH4 benthic source and bottom layer oxidation across the entire Baltic Sea using concentration and stable ...

Methane cycling in temperate forests
Carbon Balance and ManagementTemperate forest soils are considered significant methane (CH4) sinks, but other methane sources and sinks within these forests, such as trees, litter, deadwood, and the production of volatile organic compounds are not well understood.

Seven Years’ Observation of Mid-Upper Tropospheric Methane from Atmospheric Infrared Sounder
Remote Sensing, 2010 The Atmospheric Infrared Sounder (AIRS) on EOS/Aqua platform provides a measurement of global methane (CH4) in the mid-upper troposphere since September, 2002.

Limnology and Oceanography LettersDrainage canals are potential hotspots of methane (CH4) emissions from degraded peatlands in Southeast Asia. Estimates of CH4 emissions from these canals remain scarce, and both the temporal variability and pathways of CH4 emissions are uncertain.

Global Wetland Methane Emissions From 2001 to 2020: Magnitude, Dynamics and Controls
Earth's FutureThe large uncertainties in estimating CH4 emissions from wetland ecosystems, the leading natural source to the atmosphere, substantially hinder the quantification of the global CH4 budget.
