Shaped Pulses for Selective Excitation
Short rectangular pulses have broad excitation profiles (see BLOG entry for November 20, 2007) and are used for non-selective uniform excitation. These are often called "hard" pulses. Longer low power shaped pulses are used to excite specific spectral regions for selective excitation. An example of this is shown below.These are often called "soft" pulses.

how do you invert only a peak in your spectrum with a selective pulse while leaving the other peaks unperturbed?
Anonymous,
See this post of January 20, 2011

which describes the excitation profiles of shaped pulses.

Dear Phani Kumar,
I don't know what you mean by "selective relaxation".

Phani,
I don't know the answers to your questions.
