Nuclear magnetic resonance spectra of nitrogen-15 enriched octaethylporphyrin and its derivatives
Keiichi Kawano,Yukihiro Ozaki,Yoshimasa Kyogoku,Hisanobu Ogoshi,Hiroshi Sugimoto,Zen-ichi Yoshida +5 more
TL;DR: In this paper, 15N and 1H spectra of [15N4]OEPH2 in CDCl3 have indicated that the two central hydrogens move around the four nitrogen atoms rapidly enough to maintain fourfold symmetry on the n.m.r. time scale at higher temperatures, while they are fixed on two of the nitrogen atoms at lower temperatures.

Formation and stability of rare earth metalloporphyrin monolayer films on amino-terminated silanized quartz surfaces studied by ultraviolet–visible and X-ray photoelectron spectroscopy
TL;DR: It is likely that the protonated porphyrins and MOH form pi-pi complexes with a parallel stacking of the macrocycles through the electrostatic attractive interaction in theSAMs, resulting in the blue shifts of the Soret bands of the SAMs.

Method of Monitoring the Number of Amide Bonds in Peptides Using Near-Infrared Spectroscopy
Mika Ishigaki,Ito Atsushi,Hara Risa,Miyazaki Shun-Ichi,Kodai Murayama,Keisuke Yoshikiyo,Tatsuyuki Yamamoto,Yukihiro Ozaki +7 more
TL;DR: In this paper, a method of monitoring the increasing number of amide bonds with the elongation of the chain length of peptides was developed using near-infrared (NIR) spectroscopy.

Use of the product of mean intensity ratio (PMIR) technique for discriminant analysis of lycopene-rich vegetable juice using a portable NIR-excited Raman spectrometer.
TL;DR: A new method known as the product of mean intensity ratio (PMIR) analysis was developed to rapidly identify lycopene-rich samples on-site to develop a lycopenes-concentration regression model using peak intensity.
