(10 points) The bases of DNA and RNA bases have absorption maxima at approximately 260 nm, with a line width of about approximately 20 nm, which arise from * transition. Calculate the lifetime of the electronic excited states that give rise to

these electronic transitions (this is something that was discussed in class)
