Abstract

Line intensities for 109 lines in the nu1 + nu3 band of 32SO2, 4 lines in the nu1 + nu3 band of 34SO2, and 7 lines in the nu1 + nu2 + nu3 - nu2 band of 32SO2 were determined in the spectral region between 2464 cm-1 and 2503 cm-1 by applying a high resolution tunable diode laser spectrometer. The transitions from the nu1 + nu3 band of 32SO2 cover the quantum number ranges 2 </= J" </= 48, 0 </= Ka" </= 16 for lines from all branches. For the majority of lines the line intensities determined from measurements in the pressure range below 10 Torr are slightly smaller compared to the data in the HITRAN 1996 database. Averaging all our experimental data for the nu1 + nu3 band of 32SO2 a value Si Exp. = (0.94 +/- 0.01) Si HITRAN 96 was obtained. Within the experimental uncertainties the deviations between our experimental data and the HITRAN data do not show any quantum number dependence. From our experimental data we deduce for 32SO2 an integrated nu1 + nu3 band strength of (55.7 +/- 0.4).10(-20) cm-1/(molecules/cm2). For lines from the nu1 + nu2 + nu3 - nu2 hot band the situation is similar compared to the cold band; i.e., a ratio Si Exp. = (0.95 +/- 0.06) Si HITRAN 96 was obtained. For the four very weak transitions from the nu1 + ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
