問題詳情
25. The interferometer is used in FT-IR (1) to act like a grating in a monochromator, (2) toscan wavelengths from low to high, (3) to facilitate FT because the IR frequencies are toohigh to be acquired by average-cost electronics, (4) to resolve IR frequencies into a seriesof sine and cosine functions, (5) to produce an identical time-domain spectrum of muchlower frequencies. Your answer:
(A) 1,2
(B)1, 2,4
(C)3,4
(D)3, 4,5
(E)5
