  • Online Middle School Chemistry Resource

    Updated: 2012-10-31 16:13:39
    The ACS Education Division has developed a new middle school chemistry resource, "Middle School Chemistry: Big Ideas about the Very Small." This free, six-chapter resource can serve as either a stand-alone chemistry unit or as a supplement to any middle school science curriculum. "Middle School Chemistry" uses a hands-on inquiry approach along with specially designed molecular model animations, to take students from concrete experiences to an understanding of the world of atoms and molecules. Share this free resource with middle school teachers you know.

    Updated: 2012-10-31 15:52:05
    I guess you mean[tex]I(t) = I_{\inf}(1-\exp(-\frac {\tau} {T_1}))[/tex]Have you tried simply to solve for T1?

  • Help with Linearisation

    Updated: 2012-10-31 15:23:00
    Hi,I am trying to determine T1 (NMR longitudinal relaxation time) from a linear graph based on the following equation (which I need help linearising):I(t) = I(inf) [1-2exp(-tau/T1)]I need to rearrange the equation to have allow T1 to be determined from the gradient.Cheers,Mike
