Which of the following is the wave number of near infrared spectrometer?
A. 4000 – 200 cm-1
B. 200 – 10 cm-1
C. 12500 – 4000 cm-1
D. 50 – 1000 cm-1
Answer:C
Which of the following is the wave number of near infrared spectrometer?
A. 4000 – 200 cm-1 B. 200 – 10 cm-1 C. 12500 – 4000 cm-1 D. 50 – 1000 cm-1
Explanation: The wave number of near infrared spectrometer ranges between 12500 – 4000. Wavenumber is the reciprocal of wavelength.
