Abstract

The normal Raman spectrum (NRS), Fourier transform infrared spectrum (FTIRS) and surface‐enhanced Raman spectrum (SERS) of the important insecticide and acaricide fluvalinate (C~26~H~22~ClF~3~N~2~O~3~) were recorded for the first time. The spectral data are discussed in terms of characteristic chemical group frequencies and bonds. The fingerprint regions of fluvalinate vibrations that are distinct in FTIRS are identified and presented with the different fingerprint frequencies that are only characteristic to NRS. The enhancement of the benzene ring‐breathing vibration of fluvalinate in SERS is a useful mode for trace analysis for residues of this pesticide at the subnanogram level. The vibrational spectra and polarization characteristics of NRS frequencies are useful as reference spectra for this pesticide in the qualitative analysis of its residues.

## Abstract Raman spectra of an NaBF~4~ crystal were recorded and analysed. All the group theoretically expected bands were observed and assigned unambiguously. The rotational modes could be correlated with the principal moments of inertia of the BF~4~ ^βˆ’^ ion.
