#> # The spectral absorption measurements were made by R.-C. A. Fuh in the summer of 1995 using a Cary 3.
#> # The absorption values were collected using a spectral bandwidth of 1.0 nm, a signal averaging time of 0.133 sec, a data interval of 0.25 nm, and a scan rate of 112.5 nm/min.
#> #
#> # These measurements were scaled to make the molar extinction coefficient match
#> # the value of 195 cm-1/M at 257.5 nm. These values were
#> # then interpolated to report extinction coefficients at regular 1nm intervals
