| Q: |
What is the difference between SpecManager and SpecManager View Mode?
|
| A: |
ACD/Labs' SpecManager View Mode software allows users to view and search
any user created or commercial ACD/Labs spectral database. ACD/SpecManager
software, consisting of ACD/NMR Manager, MS Manager, and UV-IR Manager,
enables users to create, update, view, and search spectral databases
containing any mixture of those three techniques. View a comparison of these
two products.

| Q: |
What is the difference between the DB and non-DB versions of the NMR programs?
|
| A: |
HNMR DB is the same as HNMR; and CNMR DB is the same as CNMR except
that the DB products contain a large database supplied by ACD/Labs.
"DB" here refers to "database". The DB versions come complete with a
database of many thousands of experimentally known compounds. This database is
searchable and contains structures and references.
To date, we have over 120,000 CNMR structures and over 122,000 HNMR structures.
Both DB and non-DB programs allow you to create your own database
and, within a given database, to perform list manipulations such as
creating, adding, merging and intersecting search lists.
|
| Q: |
How do I find a single compound in the database?
|
| A: |
You need to do a structural search with all atoms explicitly designated.
For example, if you want to find benzoic acid in ACD/HNMR DB,
draw the structure as shown on the left, and then click on the
"Sub-Structure Search" button.
If you do not specify each atom (e.g., draw the structure on the right)
then the sub-structure search will include all substituted benzoic acids: some 3787 entries! (Version 5.11).
