Methodologies
Methodologies Description
Guest lecture / keynote speech In the first class it will take place a general presentation of the course: objectives, contents and organization of matter. In later sessions the basics of instrumentation, calibration, and mass spectrometry fundamentals will be explained.
Seminar General aspects of the use of the techniques of structural determination.
Workshop Use of simulation programs and resolution of practical cases of structural determination. Proposed problems will be solved by developing strategies that integrate the different spectroscopic techniques for structural elucidation. Prior to the development of some sessions, students will work out writing solutions for some of the proposed problems.
Laboratory practice Experiences involving the combination of various procedures and experimental techniques will be conducted (preparation, separation, structural determination, determination of basic physicochemical properties...). The student will carry out the scheduled experiments, and laboratory reports will be performed, including collected data and their discussion, as well as answers to proposed questions to achieve a deep understanding of the experiments.
Practical test: A practical test will be performed in the laboratory, including the solution of questions about practical subjects.
Mixed objective/subjective test Mixed test will consist of questions and problems to solve related to the topic of the lectures, workshops / seminars taught (structure determination)

Laboratory practice
Workshop
Description
The student will have the teacher's help in solving doubts and questions that may arise both in the preparation of written solutions to the problems of structural determination and the preparation of reports of work performed in the laboratory. Besides, dedicated attention can be obtained in special attention hours (tutorships), in addition teaching hours.

Students being recognized officially as partial-time and entitled not to attend the lectures will be attended in a tutorships regime (set hour with teacher in advance).

Assessment comments

Attendance to all the
sessions is mandatory. The final grade is obtained as the sum of the score on
each part: workshop, laboratory practice and tests. To pass the course a
minimum score of 5,0 (out of a possible 10) is required, with the restriction
that a minimum of 4.0 (out of a possible 10) in tests (mixed objective and
practical) and laboratory practice is mandatory. If the total sum value was
equal to or greater than 5 (out of 10) but this threshold mark was not met, the
final mark will be 4.5 (fail).

Students who failed the
practical test should be repeated in first opportunity. Any student who has
attended 51% or more of sessions (workshops / seminars + lab) will be assessed.
Regarding the second opportunity of evaluation, the qualifications of the
proofs of second opportunity will substitute to the obtained in the test of first
opportunity. The qualification of the workshops could be conserved in the second
opportunity or, in an alternative way, in the final part of the mixed test of
second opportunity, the students could realize an evaluable exercise, with
activities analogous to those developed in the workshops during the course. The
qualifications of the labs obtained at the first opportunity will be retained
for the second assessment opportunity. Students who failed the practical test
should be repeated in the second opportunity.

The students tested in the
second chance only choose the honors if the maximum number of these to the
corresponding course has not been fully covered at the first opportunity. The
teaching-learning process, including assessment, refers to a full academic
year, and therefore will start a new academic year, including all activities
and evaluation procedures that are planned for the course.

For students being recognized officially as
partial-time and/or exempted from regular attendance to the lessons, or any
other specific (official) modality, laboratory practices are mandatory and,
their realization will be carried out taking into account the time-scheduling,
personnel and instrumental resources available. In the event that the student can
not perform all activities or continuous assessment tests, the teacher take
appropriate measures to avoid prejudicing their qualification.
