This effect has been used to advantage in investigations on the structure of liquid water (101–103) and on the interactions between water and polymers (89–91). Numerous cases of Fermi and higher anharmonic resonances occur in the near infrared, leading to characteristic bands, useful for the chemical analysis of polymers.
