Possible conformational relaxation paths were explored by using different buffer gases such as neon, argon, and helium. Rotational constants were found using chirped-pulse Fourier transform microwave spectroscopy (CP-FTMW). 2-Cyanoacetic acid possesses one 14N nucleus with a nuclear quadrupole moment, giving rise to a complex hyperfine structure. To assist with spectral fitting, Autofitb was used. One stable conformer of the monomer and its complex with a water molecule have been identified on the basis of the experimental rotational constants in conjunction with DFT and ab initio predictions.","PeriodicalId":20670,"journal":{"name":"Proceedings of the 73rd International Symposium on Molecular Spectroscopy","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89429530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

POLAR RADIANT ENERGY IN THE FAR-INFRARED EXPERIMENT (PREFIRE) 远红外实验中的极辐射能(着火前)

At the poles, the greenhouse effect is minimized by the nominal cold and dry atmospheric state. This is how a significant amount of absorbed solar energy is vented back to space, acting like a thermostat. Under these conditions, the effects of surface emissivity become disproportionately large and have a significant impact on the radiative balance. Earth system models have consistently under-estimated the rapid warming occurring in the Arctic, perhaps due to poor assumptions about the nature of far-infrared spectral emissions. The Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) is a NASA Earth Ventures mission, currently in formulation, that would test the hypothesis that timevarying errors in FIR surface emissivity and atmospheric greenhouse effects bias the modeled energy balance that under-estimates Arctic warming. This presentation covers the processes involved in the energy balance, and how spectrally resolved measurements provide the means to extract critical information. We also discuss the instrument difficulties associated with remote measurements across the far-infrared, emphasizing the differing challenges associated with earth science vs. astrophysics. Finally, we provide an overview of the planned PREFIRE mission and how it would address these challenges.","PeriodicalId":20670,"journal":{"name":"Proceedings of the 73rd International Symposium on Molecular Spectroscopy","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81703645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
