FTIR−smog chamber systems were used to show that the atmospheric fate of the alkoxy radical (c-C3H5O3)O(•) is decomposition via C−O bond scission leading to the formation of H(O)COCH2OC(O)H (methylene glycol diformate). The IR spectrum of the peroxynitrate (c-C3H5O3)O2NO2...
IR spectra were recorded with a Spectrum 100 Series FTIR spectrometer (PerkinElmer, Villebon S/Yvette, France). Liquids and solids were investigated with a single-reflection attenuated total reflectance (ATR) accessory; the absorption bands are given in cm−1. NMR spectra (1H, 13C and 19F) ...
The natural bond orbital analysis of the title compound is also reported in order to understand the stability of the molecule which arises from hyper conjugative interactions and charge delocalization. The theoretical electronic absorption spectrum is also reported using the time dependent density ...
The C domain catalyzes peptide bond formation between sequential amino acids. Last, the additional thioesterase (TE) domain releases the mature peptide product via hydrolysis or cyclization3,4. Nonribosomal lipopeptides have fatty acyl chains at the N-terminus, which are introduced by a starter ...
cPteurrsepsecotfiv1ea(vCielwOs4)o, f2tah(eCclOat4io),nasn1da [a2nbd(C2lbOa4r)e]3d·CeHpi3cCteNd have been determined by in Figure 2; selected bond distances and angles are summarized in Table 1. In each case, the Ir atom adopts a distorted octahedral geometry, with the C^C^...
1. Part of the meta 'H nmr spectrum at 300 MHz and 300 K for a 1.7mol% solution of thioanisole-a-13Cin benzene-d6 solution. The smallest splittings in the observed spectrum in b are near 0.08 Hz and, according to the full analysis, are due to coupling over five bonds to the 13...
propargylamine in DMF led to morpholine- and diethylamine-functionalized monopropargylamine cage complexes, the molecules of which contain the single terminal C≡C bond. Their “click” 1,3-cycloaddition reactions in toluene withortho-carborane-(1)-methylazide catalyzed by copper(II) acetate gave ...
The IR band shape theory of the stretching mode ν s (XH…Y) in H-bonded complexes is presented. The proton in the H-bond involves motion in the Born-Oppenheimer energy potential which is accompanied by the anharmonic coupling to the low-frequency hydrogen-bridge stretching motion νσ. Bot...
IR spectra show a significant decrease in the xylose and glucose C--O bond stretching at 1050 cm-1, suggesting the formation of the corresponding for furaldehyde. EXAMPLE 3 Crosslinking To confirm that the resist functions through crosslinking of the polymer matrix, the temperature at which ...
