The full spectrum can only be viewed using a FREE account. For the NaNO3/alanine mixed systems with molar ratios of 3:1, 1:1 and 1:3, the efflorescence relative humidity (ERH) was measured to be 50.2%, 59.8% and 69.3%, respectively. Compound with free spectra: 1 NMR, 4 FTIR, and 2 Raman, SODA NITER - SODIUM NITRATE (TARAPACA, CHILE), Oxidation of Alkylarenes by Nitrate Catalyzed by Polyoxophosphomolybdates:  Synthetic Applications and Mechanistic Insights. SpectraBase Spectrum ID=E3unGMsqAOn. The discrepancies in water content for the mixed NaNO3/amino acids with molar ratios of 1:1 and 1:3 between dehydration and hydration processes at high RH could be attributed to the crystallization of amino acid-NaNO3 complex salts during dehydration and the residual amino acids. These results suggested that in each of the systems studied the addition of amino acids to aerosols could promote the crystallization of mixed droplets.

FTIR spectra were gained by collecting typical 32 scans between 4000 and 600 cm −1 at a resolution of 4 cm −1. SpectraBase Compound ID=HR3blcpYREV, Search your unknown spectrum against the world’s largest collection of reference spectra, ChemWindow structure drawing, spectral analysis, and more, Offers every student and faculty member unlimited access to millions of spectra and advanced software. The investigations on the NaNO3, glycine, alanine and their internally NaNO3/amino acid mixed particles with molar ratios of 3:1, 1:1 and 1:3 were conducted using attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR). 15N Nuclear Magnetic Resonance (NMR) Chemical Shifts of SODIUM NITRATE with properties.

Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments. View the Full Spectrum for FREE! We studied the hygroscopic properties and compositional evolution of three atmospherically relevant species, sodium nitrate (NaNO3), glycine and L-alanine (alanine).

Data compiled by: Coblentz Society, Inc. In the case of NaNO3/alanine systems, the DRH for 3:1 and 1:3 mixed particles was 78.2% and 82.7% while no deliquescence transition occurred for the 1:1 mixed particles. More information on the manner in which spectra in this collection were collected can be found here. The hygroscopic properties of mixed NaNO3/amino acids droplets were modified due to the formed amino acid-NaNO3 complex salts from the interactions of amino acids with NaNO3 in aerosols during dehydration process.

Hygroscopic properties and compositional evolution of internally mixed sodium nitrate-amino acid aerosols. The mixed NaNO3/glycine droplets with molar ratios of 3:1, 1:1 and 1:3 exhibited efflorescence transition at 52.3%, 62.6% and 63.2%RH, respectively.

Although nitrates and amino acids are ubiquitous in the atmosphere, the interactions of amino acids with nitrates on the hygroscopicity of aerosols are still not clear. National Museum of Natural History, Smithsonian Institution, Washington, D.C. However, the higher deliquescence relative humidity (DRH) with increased fraction of glycine for the mixed NaNO3/glycine (3:1, 79.2%RH; 1:1, 86.3%RH; 1:3, 86.5%RH) also indicated that glycine could inhibit the deliquescence phase transition of mixed systems.
