Vibrational, NMR spectral studies of 2-furoic hydrazide by DFT and ab initio HF methods

On the Rise: Experimental and Computational Vibrational Sum Frequency Spectroscopy Studies of Pyruvic Acid and Its Surface-Active Oligomer Species at the Air–Water Interface

“…Perkins et al reported a similar peak at ∼1660 cm –1 in the Fourier transform infrared (FTIR) spectrum of crude PPA and ZYA solutions, which the authors attributed to the CC stretching mode of ZYA. That value is somewhat higher than the frequency seen here but well within range for the CC stretching modes of furan derivatives, which extends to much lower wavenumbers, often being observed as low as ∼1500 cm –1 , and occasionally even below that. , …”

“…That value is somewhat higher than the frequency seen here but well within range for the CC stretching modes of furan derivatives, which extends to much lower wavenumbers, often being observed as low as ∼1500 cm −1111,112 and occasionally even below that. 113,114 As for the apparent shift in the CC peak position in the experimental VSF ssp spectrum when solvated by D 2 O (Figure 3A), fitting confirms that the feature at ∼1640 cm −1 undergoes a >10 cm −1 shift to the red. This shift is not explainable by subtle differences in interference effects between H 2 O and D 2 O solvation and is most likely due to H to D isotopic exchange of ZYA hydroxyl groups.…”

“…O outro precursor, a hidrazida do ácido furóico, além de ter sido alvo de um estudo sobre propriedades espectroscópicas (Vimalraj et al, 2011), aparece na literatura com potencial habilidade para entrar em células tumorais e inibir o seu crescimento, quando encontra-se complexado com metais (Silva et al, 2014) e comple-…”
