An Introduction to Computer Searching of
STN International Version
Find articles about kinetics of aquation of dichlorotetrammine or dibromotetrammine cobalt complexes.
- For Registry Numbers for
- Key Terms
- Kinetic? or Rate? (Use truncation to pick up other forms of the words such as kinetics or rates).
- Aquation or Hydrolysis
- Use (S) to combine the two groups of key words with greater precision.
- Use AND to connect the answer numbers for the cobalt complex Registry numbers with the other key terms.
- use molecular formula to find registry numbers
- search for complexes by entering the molecular formula
- search for single component substances by using the /MF code after the molecular formula
- (S) operator for more precise searching

Use the Registry file to fine Registry numbers of dichlorotetrammine or dibromotetramminecobalt complexes
=> file registry FILE 'REGISTRY' ENTERED AT 17:29:41 ON 04 JUN 96 USE IS SUBJECT TO THE TERMS OF YOUR CUSTOMER AGREEMENT COPYRIGHT (C) 1996 American Chemical Society (ACS) STRUCTURE FILE UPDATES: 31 MAY 96 HIGHEST RN 176894-09-0 DICTIONARY FILE UPDATES: 3 JUN 96 HIGHEST RN 176894-09-0 TSCA INFORMATION NOW CURRENT THROUGH DECEMBER 1995
Search the molecular formula of the complexes to find the Registry Numbers. The Registry File lists the finds in a molecular formula in the Hill order. Note that 39 complexes were found.
=> s cl2coh12n4 L1 39 cl2coh12n4
Note the if we expand in the molecular formula field we can view the different compounds that compose of the 39 files found for the previous search. But, in this case, we are interested in all the complexes so we will work with Search L1.
=> e cl2coh12n4/mf E1 1 CL2COH11N3O/MF E2 3 C2COH11N3O.CL/MF E3 4 --> CL2COH12N4/MF E4 1 CL2COH12N4.1/2O6S2/MF E5 2 CL2COH12N4.2H2O.IO3/MF E6 3 CL2COH12N4.CL/MF E7 1 CL2COH12N4.CL.1/2H2O/MF E8 2 CL2COH12N4.CL.H2O/MF E9 1 CL2COH12N4.CL2I/MF E10 2 CL2COH12N4.CLO4/MF E11 1 CL2COH12N4.H2O.NO3/MF E12 2 CL2COH12N4.HO4S/MF
=> s br2coh12n4 L2 14 br2coh12n4
Again, we can expand in the molecular formula field to view the different files composing of the complexes of our previous search.
=> e br2coh12n4/mf E1 1 BR2COD8O4.2D2O/MF E2 2 BR2COH11N3O.BR/MF E3 3 --> BR2COH12N4/MF E4 2 BR2COH12N4.BR/MF E5 1 BR2COH12N4.BRO3/MF E6 1 BR2COH12N4.CL/MF E7 1 BR2COH12N4.CLO4/MF E8 1 BR2COH12N4.I3/MF E9 1 BR2COH12N4.IO4/MF E10 1 BR2COH12N4.NO3/MF E11 1 BR2COH4O2/MF E12 1 BR2COH6N2/MF
Combine the dichloro and dibromo answers into one group to simplify searching.
=> s L1 or L2 L3 53 L1 OR L2
Use the CA file to find relevant articles now that we have found the registry number. Note that L3 will be retained when we switch databases.
=> file ca FILE 'CA' ENTERED AT 17:31:19 ON 04 JUN 96 USE IS SUBJECT TO THE TERMS OF YOUR CUSTOMER AGREEMENT COPYRIGHT (C) 1996 AMERICAN CHEMICAL SOCIETY (ACS) FILE COVERS 1967 - 29 May 1996 (960529/ED) VOL 124 ISS 23
Searching L3 finds articles about any of the cobalt complexes located in the Registry File. Using (S) limits the terms to appearing in the same subfield or sentence.
=> s L3 and (kinetic? or rate?) (S) (aquation or hydrolysis) 110 L3 570653 KINETIC? 1108960 RATE? 2918 AQUATION 39304 HYDROLYSIS 28863 (KINETIC? OR RATE?) (S) (AQUATION OR HYDROLYSIS) L4 8 L3 AND (KINETIC? OR RATE?) (S) (AQUATION OR HYDROLYSIS)
Display the indented bibliographic record of search L4, answer 1. Note terms which match the search are highlighted. Because the (S) operator was used, “kinetics” or “rate” are only highlighted when they are in the same sentence with “aquation” or “hydrolysis”
