3): two of them interpret the mass as a
proton resonance and two others as electron resonances.
Efficient decoupling over the entire band of
proton resonance frequencies is an important factor in determining the resolution and sensitivity in [sup.13]C spectroscopy [3, 4].
The
proton resonance at [delta] 1.04 ppm and 3.49 ppm were attributed to--Si--C[H.sub.2]C[[H.bar].sub.2][C.sub.8][F.sub.17] and--Si--C[H.sub.2]C[[H.bar].sub.2][C.sub.8][F.sub.17], respectively.
It incorporates a 1.4 T (60 MHz
proton resonance) rare-earth permanent magnet with enhanced homogeneity, providing spectral resolution and generating routine spectra in sec.
Available at 500 and 600 MHz
proton resonance frequencies, the AVANCE ICE has four RF channels, as well as a CryoProbe with its supporting units.
For [sup.1]H
proton resonance, the result (26) is adjusted empirically in our development for the experimentally different g factors of the proton and electron, respectively 5.5857 and 2.002.
The 'H NMR (400 MHz) spectra of the starting brominated copolymer and modified final copolymers in [CDCl.sub.3] show the disappearance of the bromomethyl
proton resonance of [-C.sub.6] [H.sub.5] ??
The single peaks at [[delta].sub.H] = 10.88 and 10.68 both are
proton resonance peaks of N-H of TTAD; the multiple peaks at [[delta].sub.H] = 7.54-7.97 are
proton resonance peaks of the benzene ring of benzoyl hydrazine.
In that way, every mass is interpreted as a
proton resonance state and expressed in continued fraction form.
The single peak at dH=10.29 and 9.84 are
proton resonance peak of N-H of NA(A), the multiple peaks at dH=7.47-7.88 are
proton resonance peaks of benzene, the triplet peaks at dH=2.17-2.20 are CH2 which is near amide
proton resonance peak, the multiple peaks at dH=1.32-1.58 are other CH2
proton resonance peaks.
Particle masses are interpreted as
proton resonance states and expressed in continued fraction form.
