Applications of Molecular Spectroscopy

When light sources pass through the diffraction grating then light splits into different wavelengths. The light source produces two types of patterns that are shown as destructive and non-destructive. The light source is in the form of quanta that is quantitation.

Question

Challenge Problem: The following are three sets of
data for the atomic mass of antimony from the work
of Willard and McAlpine':
Set 1
Set 2
Set 3
121.771 121.784 121.752
121.787 121.758 121.784
121.803 121.765 121.765
121.781 121.794
(a) Determine the mean and the standard deviation
for each data set.
(b) Determine the 95% confidence interval for each
data set.
(c) Determine whether the 121.803 value in the first
data set is an outlier for that set at the 95% confi-
dence level.
(d) Use the t test to determine whether the mean of
data set 3 is identical to that of data set 1 at the
95% confidence level.
(e) The means of all three data sets are to be compared
by ANOVA. State the null hypothesis. Determine
whether the means differ at the 95% confidence level.
(f) Pool the data and determine the overall mean and
the pooled standard deviation.
(g) Compare the overall mean of the 11l data points to
the currently accepted value. Report the absolute
error and the relative error in percent assuming the
currently accepted value is the true value.

When measuring iron in river water by spectrophotometry using the ferrozine reaction that is described in the class notes, a student finds that they cannot distinguish their samples from noise (i.e. they are below the limit of detection) when they use a 1-cm cuvette. The student makes the decision to use a 5-cm cuvette in their method instead. a) By how much should the student expect their sample measurements to increase by? Why? b) Will their reagent blank also increase by the same amount? Why or why not? 3.
