Tips on writing lab reports.


Here is a discussion on how differential calculus is used to determine how errors propagate into the final measurement.


For Experiment A1, students in PH4580 and PH6180 (6990-109) obtained excellent Raman spectra for the following linear molecules:         O2






You may access the Excel spreadsheets by clicking on the molecular formula.


For your reports, I am supplying you with a discussion of the internuclear spacings (for everyone) and (mostly intended for the graduate students) of vibrational frequencies and rotational levels for non-rigid rotators.  This includes some scanned pages from Herzberg’s classic book, Spectra of Diatomic Molecules.  [Nota Bene: On 2/13//02 I corrected two mistakes in the internuclear spacing discussion.  I had a typo (+ sign instead of – sign) in the expression for rv relative to re.  And I misread the tables from Herzberg for O2.  I read the line for O2+ (the molecular ion) instead.  The values for O2 are now correct.]
