How to retrieve documents?
1., for the need for synthetic substances, first through the CA indexing system index, and then bring up the corresponding literature. If you want to get a class of material or a response, you retrieve it through the subject index of CA. Most of the current CA is printed version, and now also has CD-ROM version of the CA, it depends on your unit, there is no money!
2. search, I usually use SCIFINDER, he can use a variety of retrieval methods, such as structural formula, CAS number, equation, and so on. If the compound is older, I also use CCD2004 (combined, chemical, dictionary), this is relatively simple, is a software, synthetic literature, physical properties of reference data. Quite good ~!
3. use PubMed search, and then use a variety of agents, passwords, Google search full-text
4., we usually use to find the synthesis method, but it should not be CA
I may be a lot of the 5. are not new, so in the web of Science in love to see what is what to do, and then find the proxy download, if it can be downloaded directly to ISI DL better use! Upstairs with the other good old bugs learn, you know! Here are Crouching.Tiger,Hidden.Dragon ah! They are all very powerful! I ~ ~ ~ ~ ~ in the study also
6., I think the literature search, the beginning of the search through CA is to search, and then find the original text. Later, slowly learned to search online, to do organic, that is, ACS, SD, RSC, wiely, Thieme these big sites, and now included are very full! With agents, basically meet the needs of scientific research, if you want to be very old, use the password! There are also some, such as heterocycles, J.heterocyclic, chemitry, arkat-usa, Japanese chemical society, orgsyn, etc. some are free of c
