emulating a frequency of color on the sun color monitor

[mckenna at think.com]

I want to emulate certain frequencies of light on a sun color monitor.
Has anyone figured out the functions R(f), G(f), and B(f) that will allow
me to emulate a frequency f from the primaries red, green, and blue?

I read that certain frequencies may require "negative" primaries.
However, if I'm lucky, I may be able to emulate a spectrum s with positive
values
