Fig. 7.9. Backscattered ICP Raman I R + I L and ROA I R − I L spectra mea-

sured for ( a ) the empty cowpea mosaic virus (CPMV) protein capsid (top pair),
( b ) the intact capsid containing RNA-2 (middle pair), and ( c ) the difference spectra
obtained by subtracting the top from the middle spectra to reveal the spectra of the
viral RNA-2 (bottom pair)
