Temperature and H/D Isotopic Effects in the IR Spectra of the Hydrogen Bond in Solid-State 2-Furanacetic Acid and 2-Furanacrylic Acid
Figure 8
Polarized IR spectra of (a) d1-2-furanacetic acid and (b) d1-2-furanacrylic acidcrystals measured at room temperature in the band frequency range. (a) 2-furanacetic acid crystal (ca. 10% H and 90% D). (I) The electric field vector parallel to the -axis, (II) The vector parallel to the *-axis (b) 2-furanacrylic acid crystal (ca. 65% H and 35% D). (I) The electric field vector parallel to the -axis, (II) The E vector parallel to the *-axis.
