Carbonate konfidens 1.0
“Several peaks with values at 1457 cm-1, 1399 cm-1, or 1340 cm-1 can also be seen, associated with the presence of CO3.”
Remineralization Potential of Three Restorative Glass Ionomer Cements: An In Vitro Study DOI: 10.3390/jcm12062434 -
Carboxyl (COOH) konfidens 1.0
“The strong characteristic absorption peak at 1550 was attributed to to the vibration of COOgroup of the galacturonic acid and those at 1399 cm-1 could correspond to COOcm-1 the vibration of group of the galacturonic acid and those at 1399 c”

C-O single bond konfidens 1.0
“The GO spectrum presents a broad band at 3192 cm-1, corresponding to the O-H stretching vibration, and peaks associated to the C = O (1734 cm-1), C-OH (1399 cm-1), C-O-C (1207 cm-1) and C-O (977 cm-1) vibrations.”

Nitrile konfidens 1.0
“The colored solution which could be due to the nitrile triple bond 1633.21cm-1 (DM) has been precisely prepared by mixing the three dyes C≡N, a band at which originates from the 1398.56cm-1 with same proportion in ultrapure water.”
